Pneumonia can be life-threatening, most commonly in older patients with comorbidities or immunocompromised patients. Author information. The most common identified viral causes of pneumonia are influenza and parainfluenza viruses. In summary, TB should be suspected in a patient with vague symptoms who possesses risk factors for TB, particularly in patients who are homeless, immunosuppressed, have a history of drug use, or have recently traveled to a TB endemic area. This case highlights an atypical presentation, where the early development of inflammatory lung injury mimicked common pneumonia. The patient with extrapulmonary features of SLE (e.g. Bronchial Neoplasms. Diffuse alveolar hemorrhage. The IVC will often reveal significant distension, with 2-2.5cm in size and < 50% collapse. Pleural effusion and pneumonia are two conditions that affect our respiratory system. Hill EE, Herijgers P, Claus P. Infective endocarditis:  changing epidemiology and predictors of 6-month mortality:  a prospective cohort study. On exam, you notice that his right lower extremity is slightly edematous compared to the left. Processes and outcomes of care for patients with community-acquired pneumonia:  results from the Pneumonia Patient Outcomes Research Team (PORT) cohort study. Pneumonia in people with lung cancer. Acute respiratory distress syndrome:  Epidemiology, pathophysiology, pathology, and etiology in adults. Pneumonia Can Often Be Seen on a Chest X-ray. 3 authors. Pneumonia is the sixth leading cause of death and tends to be more prevalent and severe in the elderly.17, 28 It is estimated that there are more than 3 million episodes of pneumonia in the United States per year, with more than half of patients being treated as outpatients, resulting in annual costs of $23 billion. The diseases that COVID-19 pneumonia may mimic can be broadly classified as infectious or non-infectious diseases (pulmonary edema, hemorrhage, neoplasms, organizing pneumonia, pulmonary alveolar proteinosis, sarcoidosis, pulmonary infarction, interstitial lung diseases, and aspiration pneumonia). Lung cancer sometimes can mimic or present as non-resolving pneumonia. Pneumonia is the sixth leading cause of death and tends to be more prevalent and severe in the elderly.17, 28 It is estimated that there are more than 3 million episodes of pneumonia in the United States per year, with more than half of patients being treated as outpatients, resulting in annual costs of $23 billion. The most common cause of pneumonia, S. pneumoniae, classically presents with a lobar infiltrate visualized on chest x-ray. Authors: Drew A. According to the U.S. Centers for Disease Control and Prevention, the first symptoms of Legionnaires’ disease can mimic the flu, but cough and chest pain can indicate the condition has progressed to pneumonia. By continuing you agree to the use of cookies. SLE is an autoimmune disorder that leads to inflammation of multiple organ systems. Benign and malignant neoplasms may present as a nonresolving pneumonia. In the patient with IE risk factors described above and multiple consolidations/infarcts on chest x-ray, strongly consider IE and obtain multiple blood cultures and echocardiogram. Patients with SLE (either diagnosed or undiagnosed) and lung involvement should be worked up for infection. In 2012, lung cancer worldwide was the most common cancer in men and the third most common cancer in women.34 In the U.S., lung cancer occurs in an estimated 225,000 patients every year and is responsible for over 160,000 deaths.35 There are many risk factors for cancer, the most notorious of which is smoking. Pulmonary involvement is common and has been observed in up to 93% of patients with SLE.20,21 Lung involvement in SLE often manifests as pleurisy, coughing, and/or dyspnea.21-23 The most common respiratory condition among patients with SLE is pleuritis, thought to be due to autoantibodies damaging the pleura itself.1 Pneumonitis may also occur in the setting of SLE. Notify me of follow-up comments by email. Chapter 65:  Pneumonia and Pulmonary Infiltrates.). Address reprint requests to Michael Lippmann, MD, Albert Einstein Medical Center, 5401 Old York Road, Klein #363, Philadelphia, PA 19141. Respir Res. These patients often have nonspecific EKGs showing left-ventricular hypertrophy, bundle branch block, or signs of a previous MI such as prominent Q waves or T wave inversions. Sometimes, the infiltrate may be in a portion of the lung that is not easily seen by standard x-ray, and other patients may have congestive heart failure or scarring in their lungs, which can mimic pneumonia. US has demonstrated tremendous utility differentiating pneumonia from other conditions. On short axis view, the LV will appear “D” shaped, with RV bowing into the LV due to elevated right-sided pressures.10-12, Endocarditis is most commonly caused by a bacterial agent, with a one-year mortality of 40%.13 The most common symptoms are intermittent fever (85%) and malaise (80%).1  Additionally, endocarditis can present with dyspnea, chest pain, cough, headache, weakness, and myalgias. It is therefore more precise to use the term nonresolving pneumonia syndrome when approach-ing these cases, since a nonresolving pneumonia He states he has felt warm at home, but he denies chest pain, abdominal pain, vomiting, and diarrhea. Pulmonary manifestations of systemic lupus erythematosus:  review of twelve cases of acute lupus pneumonitis. We are actively recruiting both new topics and authors. Pulmonary embolism (PE) occurs when a thrombus, most commonly from the venous system, embolizes to the pulmonary vasculature.7,8 Like pneumonia, the clinical presentation of a PE can vary greatly, ranging from an asymptomatic patient to an ill-appearing, dyspneic patient. Radiologic findings in pneumonia are used in conjunction with the physical exam to identify any area of consolidation. BNP will more likely be elevated in CHF exacerbations, though sepsis from pneumonia can also increase BNP.1,27, The chest x-ray findings in CHF may include prominent interstitial markings, cardiomegaly, and pleural effusions.2, US in the setting of CHF will reveal b-lines in 3 or more lung fields bilaterally, which has a +LR of 20. A lung patch on xray is surely a nonspecific finding and in most cases turns out to be pneumonia.The diagnosis is usually reached in such cases depending clinical symptoms and investigation . Clinical manifestations and diagnosis of heart failure with preserved ejection fraction. Aspiration pneumonia is another form of chemical pneumonia. Viral pneumonia may clear up on its own; however, when severe, it can be life-threatening. ANSWER: A number of non-infectious conditions, including neoplastic lesions, pulmonary oedema, pulmonary embolism, drug-induced pneumonitis, diffuse alveolar haemorrhage syndromes, cryptogenic organising pneumonia and acute eosinophilic pneumonia, may present in a similar way and mimic CAP. 8. There are a wide array of nonspecific signs and symptoms associated with the multiple forms of TB, shown in Table 5.30, Table 5. You perform a more complete review of systems and find out this gentleman has been experiencing pain in his right calf over the past week after returning from an overseas business trip. Tintinalli’s Emergency Medicine:  A Comprehensive Study Guide. A number of non-infectious conditions, including neoplastic lesions, pulmonary oedema, pulmonary embolism, drug-induced pneumonitis, diffuse alveolar haemorrhage syndromes, cryptogenic organising pneumonia and acute eosinophilic pneumonia, may present in a similar way and mimic CAP. PE can be easily confused with pneumonia, as the most common presenting symptom is dyspnea followed by pleuritic chest pain and cough.8,9 Fever can also be present in pulmonary embolism. Symptoms and Signs of Tuberculosis (Adapted from Barnes PF, et al:  Chest roentgenogram in pulmonary TB: new data on an old test. This project is rolling and you can submit an idea or write-up at any time! About 80% of coronavirus infections have no symptoms or mild symptoms consistent with the flu. Chapter 65:  Pneumonia and Pulmonary Infiltrates. Emboli in infective endocarditis:  the prognostic value of echocardiography. It’s a busy day in the ED. Treatment includes management of the underlying diseases, antibiotics for bacterial pneumonia, antifungals for fungal and metronidazole and other antiparasitic drugs for … Overview of acute pulmonary embolism in adults. We strive to reshape medical education and academia in their evolution beyond the traditional classroom. The most common signs of pneumonia include cough (79%-91%), fever (up to 75%), increased sputum (up to 65%), pleuritic chest pain (up to 50%), and dyspnea (approximately 70%).3 There are many patterns of presentation with a variety of these symptoms and physical findings, making the diagnosis at times difficult. Sometimes it's difficult to know what the exact cause of death is. Chemotherapy can weaken the body’s immune system. King Jr. TE, Kim EJ, Kinder BW. McGraw Hill Professional 2016. Acute lupus pneumonitis can closely mimic an acute infectious pneumonia both clinically and radiographically. A patient with a primary lung cancer can easily be confused with pneumonia due to the similarity of symptoms (Table 6). The patient with ARDS will appear sick and will likely require high levels of FiO2 or positive pressure ventilation if not intubated, while the severity of pneumonia varies greatly based on the patient and infectious microbe. 68, 69 Pulmonary PTLD can also radiographically mimic infectious etiologies of pneumonia. The chest x-ray shows more diffuse involvement than would be expected in a patient with pneumonia.2 US will reveal b-lines in multiple lung fields. Radiographically, SLE pneumonitis and infectious pneumonitis both present with patchy areas of consolidation, traction atelectasis, honeycomb changes, or pleural effusions [ 9 emDOCs subscribes to the Free Open Access Meducation. Table 2. TB can occur in multiple forms, including primary TB, reactivation TB, laryngeal TB, endobronchial TB, lower lung field TB infection, and tuberculoma.29 As TB affects the lungs and can present with fever, cough, or dyspnea, it is often misdiagnosed as viral or bacteria pneumonia. Thompson BT. Subhepatic appendix is a very … MacCallum NS, Evans TW. Oeltmann JE, Kammerer JS, Pevzner ES, Moonan PK. You force your exhaustion to the back of your mind as you see your next patient: a 52-year-old male with cough and shortness of breath for three days. A history of orthopnea and/or paroxysmal nocturnal dyspnea leading up to the patient’s presentation is sensitive and specific for heart failure. Horsburgh CR. Pneumonia is a very serious health condition that should be treated by a doctor as it can be fatal or land you in the hospital for extended periods of time. The death rate has remained constant at about 30 per 100,000 episodes.28 Using conventional culture techniques, the cause of community-acquired pneumonia (CAP) is determined in only approximately 50% of cases.42 A more recent prospective study using transthoracic needle aspiration to obtain a microbiologic diagnosis found Streptococcus pneumoniae to be the most common cause of CAP, accounting for 25% of all cases, with failure of conventional microbiologic techniques in one third of cases.56 The appropriate resolution rate for CAP depends to a great degree on age; comorbid factors, particularly the presence of underlying lung disease; and factors such as alcohol abuse and social strata.51 Occasionally the radiograph may show progression despite clinical improvement as exemplified by defervescence and reduction in leukocytosis.42 The virulence of the infecting organism plays an important role in resolution rates, with Staphylococcus aureus, enteric gram-negative pathogens, and Legionella taking the longest to resolve, occasionally months; Mycoplasma resolving the fastest, at 2 to 4 weeks; and Chlamydia having an intermediate resolution rate.25, 34, 42 It is useful to determine if one is dealing with a slowly resolving process (i.e., <50% resolution in 1 month), the emergence of resistance, or treatment of the wrong pathogen or process. This patient may originally be worked up for pneumonia. Castillo FJ, Anguita M, Castillo JC, et al. As you return to this 52-year-old gentleman’s room with his prescription for antibiotics, you notice that he remains tachycardic, tachypneic, and hypoxic (HR 105, RR 24, SpO2 93%). Copyright © 2001 W. B. Saunders Company. Clinical characteristics of patients with acute pulmonary embolism: data from PIOPED II. Thus, ARDS may result from a prior pneumonia leading to sepsis. He has some crackles in the lower lung bases, but has an otherwise normal physical exam. Multiple other infective and non-infective conditions can mimic community-acquired pneumonia, leading to misdiagnosis in 5–17% of cases. Worldwide Data. Collard HR, Schwarz MI. McGraw Hill Professional 2016. Positive likelihood ratios (LR) for these findings range from 15.6 to 16.8, with negative LR’s of 0.03 to 0.07.5,6  Please see a prior emDocs.net post on the use of US in pneumonia: http://www.emdocs.net/ultrasound-for-pneumonia-in-the-ed/.

Other findings on chest x-ray found in various organisms include pleural effusions, basilar infiltrates, interstitial infiltrates, or abscesses.1,2,4 However, each agent can present multiple ways on chest x-ray, and many patients may not demonstrate the classic radiographic findings, especially elderly and immunocompromised patients with weakened immune systems. Have feedback or suggestions on how we can improve the site? 8th ed. Pneumonia can happen on its own or as a result of a complication of other infections like the flu. His past medical history includes hypertension and hyperlipidemia. Acute Respiratory Distress Syndrome (ARDS) is acute, diffuse, inflammatory lung injury that carries high rates of morbidity, ranging from 26 to 58%.35,36 ARDS stems from diffuse alveolar damage and lung capillary endothelial injury, leading to increased capillary permeability and pulmonary edema.1 This disease manifests with respiratory distress, with patients often displaying tachycardia, tachypnea, hypoxemia, and dyspnea.37 Arterial blood gas analysis shows hypoxemia in addition to acute respiratory alkalosis and increased alveolar-arterial oxygen gradient (though ABG is usually not required in the ED). http://www.emdocs.net/ultrasound-for-pneumonia-in-the-ed/, http://www.who.int.proxy.library.vanderbilt.edu/tb/publications/global_report/en/, http://www.wcrf.org/int/cancer-facts-figures/worldwide-data, emDOCs.net – Emergency Medicine EducationMedical Malpractice Insights: Learning from mistakes and dodging bullets - emDOCs.net - Emergency Medicine Education, emDOCs Podcast – Episode 20: Perspectives on Failure with Rob Orman, Non-Pregnant Vaginal Bleeding: Differential Diagnosis, Presentation, Evaluation, and Management, EM@3AM: Transfusion Related Acute Lung Injury, Ultrasound G.E.L. If a person has lung cancer and gets pneumonia, the prognosis and life expectancy is poor. Pneumonia is defined as an acute infection of the pulmonary alveoli. If concerned for ARDS, be ready to intubate the patient for clinical course/oxygenation and admit to the ICU. One of the most important aspects to not miss is the patient with multiple infiltrates on chest x-ray, as a dreaded complication of IE is septic emboli. Pulmonary manifestations of systemic lupus erythematosus. Siegel MD. Steckelberg JM, Murphy JG, Ballard D, et al. Health conditions that can mimic chronic or recurrent pneumonia [4]: Chronic eosinophilic pneumonia; Pneumonitis; Coal worker’s pneumoconiosis; Interstitial pulmonary fibrosis; Chronic bronchitis; Treatment. empiric therapy. The classic presentation of pneumonia is a cough productive of purulent sputum, shortness of breath, and fever. Maintenance of a high index of suspicion and knowledge of these atypical locations is crucial. If COVID-19 spreads to the lungs, it can cause pneumonia. Clinical presentation, histology, survival, and outcome. A number of non-infectious conditions, including neoplastic lesions, pulmonary oedema, pulmonary embolism, drug-induced pneumonitis, diffuse alveolar haemorrhage syndromes, cryptogenic organising pneumonia and acute eosinophilic pneumonia, may present in a similar way and mimic CAP. Pneumonia can be dangerous for … 2014;7(1):115-21. These include pulmonary embolism, endocarditis, vasculitis, acute decompensated heart failure, tuberculosis, primary lung cancer, and acute respiratory distress syndrome.

X-ray has a sensitivity of 46-77% in diagnosing pneumonia. Perera, T. Mailhot, D. Riley, and D. Mandavia, “The RUSH exam: rapid ultrasound in Shock in the evaluation of the critically ill,”, P. Borloz, W. J. Frohna, C. A. Phillips, and M. S. Antonis, “Emergency department focused bedside echocardiography in massive pulmonary embolism,”, Madan and C. Schwartz, “Echocardiographic visualization of acute pulmonary embolus and thrombolysis in the ED,”, Murdoch DR, Corey GR, Hoen B. Pneumonia caused by the new coronavirus can show up as distinctive hazy patches on the outer edges of the lungs, indicated by arrows. While it is tempting to diagnose pneumonia in a patient with a classic presentation (fever, cough, shortness of breath) and a supportive chest x-ray, what else should be considered? Chest 1974; 65:299-306 and Chute CG, et al. Matthay RA, Schwarz MI, Petty TL, et al. not resolving over course of 1-2 weeks despite being treated with antibiotics. World Cancer Research Fund International. Diagnostic performance of lung ultrasound in the diagnosis of pneumonia: a bivariate meta-analysis. It is the 7th leading cause of death in the U.S. and the number one cause of death from infectious disease in the U.S.1   The annual incidence of community acquired pneumonia (CAP) ranges from 2 to 4 million, resulting in an estimated annual 500,000 hospitalizations.1  Pneumonia is broken into several categories: community-acquired (CAP), hospital-acquired, healthcare-associated (HCAP), and ventilator-associated (VAP) (Table 1). This wide variation in symptoms and presentation provides potential for misdiagnosis, especially if other conditions are not considered. Clinical manifestations and complications of pulmonary tuberculosis. Symptoms of lung cancer at presentation. Post‐transplant lymphoproliferative disease (PTLD) may present with lung/thoracic involvement including pulmonary nodules and mediastinal adenopathy, especially in lung/heart‐lung transplant recipients. Diffuse alveolar hemorrhage (DAH) is one of the most life-threatening conditions in SLE. Hampton’s Hump (peripheral wedge-shaped opacity with base against pleural surface) and Westermark’s Sign (focus of oligemia and vessel collapse distal to the PE) are classic findings in the PE radiograph, but they lack sensitivity. Diagnosis includes the Duke Criteria. Pneumonia can cause the small air sacs in your lungs, known as alveoli, to fill with fluid. Epidemiology, risk factors, and microbiology of infective endocarditis. Vasculitis (Systemic Lupus Erythematosus), A vasculitis that often manifests with pulmonary involvement is systemic lupus erythematosus (SLE). *Bonus: What can potentially assist providers? Physical exam may reveal an S3 or S4 heart sound, elevated jugular venous pressures, lower extremity edema, and crackles indicating interstitial pulmonary edema on auscultation of the lungs. Consultation with rheumatology and the ICU is recommended due to the potential for rapid decompensation. Global Tuberculosis Report 2014. It is estimated that a microbial agent cannot be identified in nearly half of cases of CAP.1 The “typical” pathogens in patients hospitalized with pneumonia include S. pneumoniae and H. influenza, with S. pneumoniae being the most common. Patients often require intubation, ICU admission, and high dose steroids.24-26, A patient with heart failure exacerbation can present similarly to a patient with pneumonia, particularly if a patient has undiagnosed heart failure. Rosen’s Emergency Medicine:  Concepts and Clinical Practice and Maloney G, Anderson E, Yealy DM. While pneumonia classically presents with a fever, cough, and shortness of breath, the presentation can vary widely in adults. Barnes PF, et al: Chest roentgenogram in pulmonary TB:  new data on an old test. Bacteria from the stomach or mouth can also cause bacterial pneumonia. As TB has many forms, the chest x-ray in TB can vary and may not be all that helpful in differentiating TB from pneumonia. Click below to contact us or find us on Twitter, Facebook or Google+. Clinical characteristics of patients with acute pulmonary embolism:  data from PIOPED II. Published by Elsevier Inc. All rights reserved. Pneumonia is a common lung infection. (Modified from: Hyde, L, Hyde, CI. Elderly or debilitated patients in particular can present with non-specific complaints, such as altered mental status without the classic symptoms.1,2 In addition, pneumonia may cause lightheadedness, malaise, weakness, headache, nausea/vomiting, joint pain, and rash. Patients with acute decompensated heart failure most commonly present with cough, shortness of breath, fatigue, and/or peripheral edema. Rubenfeld GD, Caldwell E, Peabody E, et al. Pulmonary manifestations of systemic lupus erythematosus in adults. These patients present with severe shortness of breath, hemoptysis, and diffuse patchy infiltrates on chest x-ray. Infective endocarditis in the aging patient. Lung tumors can be diagnosed as pneumonia when they are first detected on a chest x-ray. The most common symptoms and their frequency are shown in Table 3. Stein PD, Beemath A, Matta F, et al. As the presentation of PE is nonspecific, clinical gestalt and risk stratification are useful. Specifically, embolization can lead to stroke, paralysis, blindness, ischemia of the extremities, splenic or renal infarction, pulmonary emboli, or an acute myocardial infarction.18 In particular, septic emboli from the right heart to the pulmonary arteries can lead to a toxic-appearing patient with fever and shortness of breath. Post was not sent - check your email addresses! Patients with acute lupus pneumonitis present with a rapid onset of fever, cough, and dyspnea, with elevation of serum antinuclear antibodies and anti-DNA antibodies.22,23. Fighting off pneumonia can be very difficult for mesothelioma patients. These are called differential diagnoses — serious medical conditions that mimic the symptoms of less serious conditions. Long, BS (@drew2232, Vanderbilt University School of Medicine, US Army) and Brit Long, MD (@long_brit, EM Chief Resident at SAUSHEC, USAF) // Edited by: Alex Koyfman, MD (@EMHighAK, EM Attending Physician, UTSW / Parkland Memorial Hospital) & Justin Bright, MD (@JBright2021, Senior Staff Physician, Henry Ford Hospital). A chest CT reveals a large right-sided segmental PE. Unfortunately, many of these diagnoses are not even considered in a patient with a classic presentation for pneumonia until the patient fails to improve with initial antibiotic management. Evaluate the patient for signs/symptoms of PE including shortness of breath with pleuritic chest pain, tachypnea, and leg swelling in the setting of risk factors such as recent travel history, prior history of thrombosis, family history of thrombosis, or history of cancer. The chest x-ray in patients with a primary lung cancer may display a solitary nodule, an interstitial infiltrate, or may be normal.2. 2014;15:50. ), Acute pulmonary infection in a patient who is not hospitalized or residing in a long-term care facility 14 or more days before presentation, New infection occurring 48 hours or more after hospital admission, Patients hospitalized ≥ 2 days within past 90 days, Pneumonia can be caused by bacteria, viruses, or fungi. Diagnostic approach to community-acquired pneumonia in adults. Internal Medicine Department, Centro Hospitalar do Baixo Vouga, Aveiro, Portugal. The important aspect of not missing PE is first considering it. Community-acquired pneumonia (CAP) can be caused by viruses, bacteria and fungi (Figure 1). Thompson BT. Saunders 2014.

Tintinalli’s Emergency Medicine:  A Comprehensive Study Guide. Changes in the Clinical Profile, Epidemiology and Prognosis of Left-sided Native-valve Infective Endocarditis Without Predisposing Heart Conditions. Abnormal cells in lung tissue that multiply causing malignant tumors in the lung(s) cause lung cancer. The diseases that COVID-19 pneumonia may mimic can be broadly classied as infectious or non-infectious diseases (pulmonary edema, hemorrhage, neoplasms, organizing pneumonia, pulmonary alveolar proteinosis, sarcoidosis, pulmonary infarction, interstitial lung diseases, and aspiration pneumonia). Contracting pneumonia before mesothelioma surgery may delay or cancel the procedure, depending on the how sick the patient gets. We summarize the Clinical presentation, evaluation, and diagnosis of the adult with suspected acute pulmonary embolism. Cantrell M, Yoshikawa TT. If signs and/or symptoms are present and concerning, do not hesitate to begin the workup for PE. Connective tissue diseases:  In:  Interstitial Lung Disease, 5. ... Disease in atypical organ locations can mimic other pathologies, hampering the right diagnosis. Clinically, both present with dyspnea, fever, and chest pain. Echocardiogram may reveal depressed contractility if systolic dysfunction is present.28, Tuberculosis (TB) is currently the world’s second leading infectious cause of death.1 The lungs are the major site for infection with Mycobacterium tuberculosis. [. Tuberculosis and substance abuse in the United States, 1997-2006. Pneumonia can cause death due to heart failure or respiratory failure. Fine MJ, Stone RA, Singer DE et al. If considering a primary lung malignancy in a patient whose presentation is consistent with pneumonia, more definitive imaging including CT of the chest may be warranted. Unfortunately, many of these conditions are not considered until the patient fails to improve after treatment with antibiotics. Mimics of Pneumonia (Adapted from Marx JA. Risk factors for IE are shown below in Table 4. Pozniak A. Sexton DJ. MIMICS OF PNEUMONIA Bronchiolitis Obliterans Organizing Pneumonia. However, it is often challenging to differentiate between these in the ED, and many patients will not have an etiologic agent identified even after inpatient evaluation. Various viruses, bacteria, and fungi can cause pneumonia. Alveolar hemorrhage in systemic lupus erythematosus:  a cohort review. This has been described in 13 to 44% of patients with IE.18,19 Septic emboli can lead to damage in the systemic or pulmonary artery circulation, depending on left vs. right-sided disease. This blog aims to disrupt how medical providers and trainees can gain public access to high-quality, educational content while also engaging in a dialogue about best-practices in EM and medical education. Complications and outcome of infective endocarditis. The following should be considered in a patient presenting with signs of pneumonia: Your email address will not be published. Are there other diagnoses you should consider? 28 Using … When a person diagnosed with mesothelioma gets pneumonia, it may delay other cancer treatments, too. But bacteria, fungi, and other microorganisms can also cause it. Pires JR 1, Moreira MJ 1, Martins M 2, Neves C 1. Classification of Pneumonia (Adapted from Maloney G, Anderson E, Yealy DM. A chest radiograph will typically reveal bilateral alveolar infiltrates, and classically, no cardiomegaly is seen.2. The cause can be bacteria, a virus, or fungi. This review evaluates history and physical examination findings of pneumonia and several conditions that mimic pneumonia. The inflammation comes from the toxic effects of stomach acid and enzymes on lung tissue. Having said that, if someone with high blood pressure or other heart issues has symptoms of pneumonia, he or she needs to be extra careful. You order a chest x-ray, which demonstrates a right lower lobe infiltrate. Again, the chest x-ray may demonstrate multiple infarcts or consolidations. Furthermore, these symptoms will progress over time and may include symptoms less commonly seen in pneumonia (weight loss, bone pain, or voice hoarseness). Hu QJ, Shen YC, Jia LQ, et al.
