Pneumonia can cause the small air sacs in your lungs, known as alveoli, to fill with fluid. 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. Castillo FJ, Anguita M, Castillo JC, et al. Community-acquired pneumonia (CAP) can be caused by viruses, bacteria and fungi (Figure 1). Notify me of follow-up comments by email. 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. 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. The following should be considered in a patient presenting with signs of pneumonia: Your email address will not be published. Tintinalli’s Emergency Medicine:  A Comprehensive Study Guide. Internal Medicine Department, Centro Hospitalar do Baixo Vouga, Aveiro, Portugal. 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? Address reprint requests to Michael Lippmann, MD, Albert Einstein Medical Center, 5401 Old York Road, Klein #363, Philadelphia, PA 19141. Sexton DJ. Saunders 2014. Author information. Klebsiella may present with diffuse, patchy infiltrates. When a person diagnosed with mesothelioma gets pneumonia, it may delay other cancer treatments, too. valvular or congenital), Marx JA. The examination may reveal bronchial or decreased breath sounds, dullness on percussion, rales, rhonchi, or wheezing. Cancer 1985; 56:2107-2111). Save my name, email, and website in this browser for the next time I comment. Incidence and outcomes of acute lung injury. In PE, US may reveal RV strain with dilated RV and free wall hypokinesis and normal RV apical contractility (McConnell Sign). 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). Rubenfeld GD, Caldwell E, Peabody E, et al. Zamora MR, Warner ML, Tuder R, Schwarz MI. 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). Horsburgh CR. Risk factors for IE are shown below in Table 4. The diagnosis of ARDS is complicated, as the most common cause or ARDS is sepsis. Collard HR, Schwarz MI. Pneumonia can cause death due to heart failure or respiratory failure. A chest x-ray in a person with pneumonia does not always have the characteristic “infiltrate” early in the course of the illness. 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. 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. Post‐transplant lymphoproliferative disease (PTLD) may present with lung/thoracic involvement including pulmonary nodules and mediastinal adenopathy, especially in lung/heart‐lung transplant recipients. A patient with flu-like symptoms (cough, myalgias, etc.) Pneumonia is defined as an acute infection of the pulmonary alveoli. Unusual Pneumonia Mimic. 1. Since patients with SLE are often immunosuppressed due to immunomodulatory therapy and the disease itself, they are at a much higher risk of infection with both typical and opportunistic agents. Diffuse alveolar hemorrhage (DAH) is one of the most life-threatening conditions in SLE. Symptoms of lung cancer at presentation. 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. If signs and/or symptoms are present and concerning, do not hesitate to begin the workup for PE. A history of orthopnea and/or paroxysmal nocturnal dyspnea leading up to the patient’s presentation is sensitive and specific for heart failure. 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. Authors: Drew A. Overview of acute pulmonary embolism in adults. The most commonly reported behavioral risk factor among patients with TB in the U.S. is substance abuse (including drugs, tobacco, and alcohol).31 Other risk factors include malnutrition, systemic disease (silicosis, malignancy, diabetes, renal disease, celiac disease, or liver disease), or patients who are immunocompromised or homeless.32  Additionally, TB should be considered when a patient has a history of recent travel to an area where TB is endemic (Africa, the Middle East, Southeast and East Asia, and Central and South America).33. Aspiration pneumonia is another form of chemical pneumonia. US has demonstrated tremendous utility differentiating pneumonia from other conditions. Diagnostic approach to community-acquired pneumonia in adults. Complications and outcome of infective endocarditis. Radiographically, SLE pneumonitis and infectious pneumonitis both present with patchy areas of consolidation, traction atelectasis, honeycomb changes, or pleural effusions [ 9 We summarize the imaging findings of COVID-19 and the aforementioned lung … Pneumonia can range from a mild to serious or life-threatening … Bacteria from the stomach or mouth can also cause bacterial 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. Chapter 65:  Pneumonia and Pulmonary Infiltrates. 8, Maloney G, Anderson E, Yealy DM. Matthay RA, Schwarz MI, Petty TL, et al. As a result, when pneumonia fails to respond to treatment, the question becomes whether or not the diagnosis of pneumonia is even correct, since many conditions can mimic pneu-monia. Andrade C, Mendonca T, Farinha F, et al. He has some crackles in the lower lung bases, but has an otherwise normal physical exam. A PE most commonly has non-specific chest x-ray findings (atelectasis, pleural effusion, peripheral infarct/consolidation, elevated hemidiaphragm) or is normal.2  That being said, while a normal chest x-ray is helpful in distinguishing PE from pneumonia, a normal chest x-ray does not definitively exclude pneumonia or pulmonary embolism. Clinical manifestations and complications of pulmonary tuberculosis. with the risk factors shown in Table 4, warrants further evaluation for IE. not resolving over course of 1-2 weeks despite being treated with antibiotics. Patients with SLE (either diagnosed or undiagnosed) and lung involvement should be worked up for infection. *Bonus: What can potentially assist providers?

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. Viral pneumonia may clear up on its own; however, when severe, it can be life-threatening. Dynamic air bronchograms (those that move) are considered pathognomonic for pneumonia. 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. 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 chest x-ray in patients with a primary lung cancer may display a solitary nodule, an interstitial infiltrate, or may be normal.2. Dellaripa PF, Danoff Sonye. Contact us at editors@emdocs.net.

Vasculitis (Systemic Lupus Erythematosus), A vasculitis that often manifests with pulmonary involvement is systemic lupus erythematosus (SLE). If concerned for ARDS, be ready to intubate the patient for clinical course/oxygenation and admit to the ICU. Furthermore, these symptoms will progress over time and may include symptoms less commonly seen in pneumonia (weight loss, bone pain, or voice hoarseness). Epidemiology, risk factors, and microbiology of infective endocarditis. Sometimes it's difficult to know what the exact cause of death is. Pneumonia is a lung infection that leads to breathing difficulties and fluid in the lungs. The “typical” pathogens are thought to account for about half of cases.1 “Atypical” pathogens include Legionella, Mycoplasma, and Chlamydia. World Health Organization. Aspiration means that you breathe oral secretions or stomach contents into your lungs. Pleural effusion and pneumonia are two conditions that affect our respiratory system. 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. 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.

It’s a busy day in the ED. The important aspect of not missing PE is first considering it. 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. 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. (Modified from: Hyde, L, Hyde, CI. One month prior to presentation, This case highlights an atypical presentation, where the early development of inflammatory lung injury mimicked common pneumonia. This project is rolling and you can submit an idea or write-up at any time! Lung cancer sometimes can mimic or present as non-resolving pneumonia. Risk factors such as sepsis, aspiration, and multiple transfusions are commonly seen with ARDS.38 Other risk factors for ARDS include alcohol abuse, trauma, and smoke inhalation. The most common cause of pneumonia, S. pneumoniae, classically presents with a lobar infiltrate visualized on chest x-ray. A chest CT reveals a large right-sided segmental PE. Epidemiology of tuberculosis. Table 1. Diagnosis includes the Duke Criteria. Chest. Oeltmann JE, Kammerer JS, Pevzner ES, Moonan PK. Tintinalli’s Emergency Medicine:  A Comprehensive Study Guide.

Diagnostic performance of lung ultrasound in the diagnosis of pneumonia: a bivariate meta-analysis. About 80% of coronavirus infections have no symptoms or mild symptoms consistent with the flu. Siegel MD. On physical exam, patients with ARDS often have diffuse crackles on auscultation of the lungs. Thus, ARDS may result from a prior pneumonia leading to sepsis. Other organisms, such as Staphylococcus aureus pneumonia can be seen on chest x-ray as extensive infiltration and effusion or empyema. 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.

Needless to say that a ZN stain to look repeatedly for acid fast bacilli will be vital in ruling out TB which can mimic many of the pneumonias in presentation. Benign and malignant neoplasms may present as a nonresolving pneumonia. There are many mimics of such patches like tuberculosis, collapsed lung lobe, fibrosis, lung nodules abscess, occupational diseases and fungal infections etc.The list is quiet long. 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. 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. What can mimic pneumonia? According to the Centers for Disease Control and Prevention (CDC), COVID-19 is a respiratory illness. [. 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). As you write the diagnosis of “pneumonia” on the discharge form and write a prescription for antibiotics, you pause. As Table 2 shows, many conditions can be confused for pneumonia based on the history, physical exam, and radiographic findings.

Pneumonia can be life-threatening, most commonly in older patients with comorbidities or immunocompromised patients. Infective endocarditis (IE) can easily be confused with pneumonia in a patient presenting with fever and dyspnea or chest pain. These are called differential diagnoses — serious medical conditions that mimic the symptoms of less serious conditions. Pneumonia can happen on its own or as a result of a complication of other infections like the flu. The history and physical exam may be enough to differentiate a heart failure exacerbation from pneumonia. 68, 69 Pulmonary PTLD can also radiographically mimic infectious etiologies of pneumonia. Classification of Pneumonia (Adapted from Maloney G, Anderson E, Yealy DM. Lung cancer and pneumonia have similar symptoms, and both can be fatal.

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. Unfortunately, many of these conditions are not considered until the patient fails to improve after treatment with antibiotics. Pneumonia in people with lung cancer. Hansen-Flaschen J, Siegel MD. 94:316, 1988.

We summarize the Subhepatic appendicitis presents a diagnostic challenge and its clinical presentation may mimic that of other entities. Consultation with rheumatology and the ICU is recommended due to the potential for rapid decompensation. 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.
