Barnes PF, et al: Chest roentgenogram in pulmonary TB:  new data on an old test. malar rash, oral ulcers, polyserositis, renal insufficiency, cytopenia, thrombophilia, lymphadenopathy, splenomegaly, or arthritis) and signs of lung involvement warrants treatment for infection and worsening vasculitis. Acute respiratory distress syndrome:  Clinical features and diagnosis in adults. Pneumonia is a common lung infection. This case highlights an atypical presentation, where the early development of inflammatory lung injury mimicked common pneumonia. Community-acquired pneumonia (CAP) can be caused by viruses, bacteria and fungi (Figure 1).

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. He states he has felt warm at home, but he denies chest pain, abdominal pain, vomiting, and diarrhea. 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. Infective endocarditis (IE) can easily be confused with pneumonia in a patient presenting with fever and dyspnea or chest pain. Alveolar hemorrhage in systemic lupus erythematosus:  a cohort review. Fine MJ, Stone RA, Singer DE et al. King Jr. TE, Kim EJ, Kinder BW. Table 6. Diffuse alveolar hemorrhage (DAH) is one of the most life-threatening conditions in SLE. 13-17. If concerned for ARDS, be ready to intubate the patient for clinical course/oxygenation and admit to the ICU. Thompson BT. 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. Copyright © 2001 W. B. Saunders Company. The remainder of this discussion will focus on differentiating each of these from 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. 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. Contact us at editors@emdocs.net. The history and physical exam may be enough to differentiate a heart failure exacerbation from pneumonia. He has experienced several episodes of nausea. 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. If a person has lung cancer and gets pneumonia, the prognosis and life expectancy is poor. As Table 2 shows, many conditions can be confused for pneumonia based on the history, physical exam, and radiographic findings. Pneumonia is defined as an acute infection of the pulmonary alveoli. Ultrasound (US)! Saunders 2014. Contracting pneumonia before mesothelioma surgery may delay or cancel the procedure, depending on the how sick the patient gets. Lung ultrasound for the diagnosis of pneumonia in adults: a systematic review and meta-analysis. 1. Epidemiology of tuberculosis. Am J Med. The most common identified viral causes of pneumonia are influenza and parainfluenza viruses. The chest x-ray in patients with lung cancer varies depending on the type and stage of cancer. (Modified from: Hyde, L, Hyde, CI. Classification of Pneumonia (Adapted from Maloney G, Anderson E, Yealy DM. The lung infection primarily affects the tiny air sacs of the lungs, causing a number of respiratory symptoms that mimic a bad cough, flu, and fever.

In addition to pneumonia, you decide to begin to work up this gentleman for a possible deep venous thrombosis and pulmonary embolism. 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 . 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. In PE, US may reveal RV strain with dilated RV and free wall hypokinesis and normal RV apical contractility (McConnell Sign). Pleural effusion and pneumonia are two conditions that affect our respiratory system. A patient with a primary lung cancer can easily be confused with pneumonia due to the similarity of symptoms (Table 6). Diffuse alveolar hemorrhage. 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. Symptoms and Signs of Tuberculosis (Adapted from Barnes PF, et al:  Chest roentgenogram in pulmonary TB: new data on an old test. As you write the diagnosis of “pneumonia” on the discharge form and write a prescription for antibiotics, you pause. 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. If COVID-19 spreads to the lungs, it can cause pneumonia. Of the diagnoses listed in Table 2, several of these carry high potential for morbidity and mortality. Powered by Gomalthemes. Post was not sent - check your email addresses! 3 authors. 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. 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. Unusual Pneumonia Mimic. Lung tumors can be diagnosed as pneumonia when they are first detected on a chest x-ray. 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. Pneumonia can happen on its own or as a result of a complication of other infections like the flu. Andrade C, Mendonca T, Farinha F, et al. 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.

Rosen’s Emergency Medicine:  Concepts and Clinical Practice and Maloney G, Anderson E, Yealy DM. 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. These include pulmonary embolism, endocarditis, vasculitis, acute decompensated heart failure, tuberculosis, primary lung cancer, and acute respiratory distress syndrome. Such conditions may even be emergencies, like appendicitis. We use cookies to help provide and enhance our service and tailor content and ads.

Overview of acute pulmonary embolism in adults. 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. Pneumonia can cause death due to heart failure or respiratory failure. The most common symptoms and their frequency are shown in Table 3. 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. Again, the chest x-ray may demonstrate multiple infarcts or consolidations. Aspiration pneumonia is another form of chemical pneumonia. Clinical manifestations and complications of pulmonary tuberculosis. It is therefore more precise to use the term nonresolving pneumonia syndrome when approach-ing these cases, since a nonresolving pneumonia A chest x-ray in a person with pneumonia does not always have the characteristic “infiltrate” early in the course of the illness. Other organisms, such as Staphylococcus aureus pneumonia can be seen on chest x-ray as extensive infiltration and effusion or empyema.

When a person diagnosed with mesothelioma gets pneumonia, it may delay other cancer treatments, too. Discussion with the oncology service is advised. US findings with pneumonia include air bronchograms, b-lines, consolidations, pleural line abnormalities, and pleural effusions. 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. You order a chest x-ray, which demonstrates a right lower lobe infiltrate. Chapter 65:  Pneumonia and Pulmonary Infiltrates. You have a full waiting room and multiple patients who have been roomed but not seen. 68, 69 Pulmonary PTLD can also radiographically mimic infectious etiologies of pneumonia. Shown is a CT scan from a 65-year-old man in China with COVID-19. Have feedback or suggestions on how we can improve the site? The classic presentation of pneumonia is a cough productive of purulent sputum, shortness of breath, and fever. Bacteria from the stomach or mouth can also cause bacterial pneumonia. 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. Affiliations. Sorry, your blog cannot share posts by email. Acute lupus pneumonitis can closely mimic an acute infectious pneumonia both clinically and radiographically. A history of orthopnea and/or paroxysmal nocturnal dyspnea leading up to the patient’s presentation is sensitive and specific for heart failure. Epidemiology of acute lung injury. We are actively recruiting both new topics and authors. Treatment includes management of the underlying diseases, antibiotics for bacterial pneumonia, antifungals for fungal and metronidazole and other antiparasitic drugs for … 43-year-old female with an active smoking history of 20 years presented to us with complaints of fever, cough, fatigue, headache and shortness of breath.

Tuberculosis and substance abuse in the United States, 1997-2006. 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. Subhepatic appendicitis presents a diagnostic challenge and its clinical presentation may mimic that of other entities. valvular or congenital), Marx JA. Symptoms of lung cancer at presentation. Rosen’s Emergency Medicine:  Concepts and Clinical Practice. X-ray has a sensitivity of 46-77% in diagnosing pneumonia. A patient with flu-like symptoms (cough, myalgias, etc.) The chest x-ray in patients with a primary lung cancer may display a solitary nodule, an interstitial infiltrate, or may be normal.2. 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. emDOCs subscribes to the Free Open Access Meducation. Unfortunately, many of these conditions are not considered until the patient fails to improve after treatment with antibiotics. Thompson BT. 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. 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. 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. Lung cancer sometimes can mimic or present as non-resolving pneumonia. Pneumonia can cause the small air sacs in your lungs, known as alveoli, to fill with fluid. Benign and malignant neoplasms may present as a nonresolving pneumonia. 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. US may reveal valvular vegetation(s) and/or regurgitation. 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. His vital signs include HR 103, RR 24, BP 128/72, T 99.8, and SpO2 95% on room air. Pneumonia Can Often Be Seen on a Chest X-ray. This wide variation in symptoms and presentation provides potential for misdiagnosis, especially if other conditions are not considered. Patients with SLE (either diagnosed or undiagnosed) and lung involvement should be worked up for infection. 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. 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. Respir Res. World Health Organization. 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. Incidence and outcomes of acute lung injury. Castillo FJ, Anguita M, Castillo JC, et al. What is key in primary lung cancer is these symptoms have a more insidious onset than the relatively more acute onset of symptoms in pneumonia. There are a wide array of nonspecific signs and symptoms associated with the multiple forms of TB, shown in Table 5.30, Table 5. 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. 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. Chemotherapy can weaken the body’s immune system. Chest. Pneumonia is a lung infection that leads to breathing difficulties and fluid in the lungs. On physical exam, patients with ARDS often have diffuse crackles on auscultation of the lungs. Click below to contact us or find us on Twitter, Facebook or Google+. Borlaug BA. Stein PD, Beemath A, Matta F, et al. 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.
