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 death rate has remained constant at about 30 per 100,000 episodes. Shown is a CT scan from a 65-year-old man in China with COVID-19.

Infective endocarditis (IE) can easily be confused with pneumonia in a patient presenting with fever and dyspnea or chest pain. Diffuse alveolar hemorrhage (DAH) is one of the most life-threatening conditions in SLE. Affiliations. The chest x-ray in patients with lung cancer varies depending on the type and stage of cancer. Complications and outcome of infective endocarditis. Pneumonia in people with lung cancer. Pneumonia can cause death due to heart failure or respiratory failure. Bacteria, viruses, and fungi cause pneumonia. In PE, US may reveal RV strain with dilated RV and free wall hypokinesis and normal RV apical contractility (McConnell Sign). You can get pneumonia as a complication of viral infections such as COVID-19 or the flu, or even a common cold. As the presentation of PE is nonspecific, clinical gestalt and risk stratification are useful. Radiologic findings in pneumonia are used in conjunction with the physical exam to identify any area of consolidation. MacCallum NS, Evans TW.

Again, the chest x-ray may demonstrate multiple infarcts or consolidations. Sometimes it's difficult to know what the exact cause of death is. If signs and/or symptoms are present and concerning, do not hesitate to begin the workup for PE. ), In differentiating TB from pneumonia, it is important to assess the patient for risk factors for TB. ), 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. 68, 69 Pulmonary PTLD can also radiographically mimic infectious etiologies of pneumonia. Chapter 65:  Pneumonia and Pulmonary Infiltrates. If COVID-19 spreads to the lungs, it can cause pneumonia. 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.

We summarize the The chest x-ray in patients with pneumonia can vary greatly. Steckelberg JM, Murphy JG, Ballard D, et al. 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. Lung cancer and pneumonia have similar symptoms, and both can be fatal. Hu QJ, Shen YC, Jia LQ, et al. Clinical manifestations and diagnosis of heart failure with preserved ejection fraction. His past medical history includes hypertension and hyperlipidemia. 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.

In addition to pneumonia, you decide to begin to work up this gentleman for a possible deep venous thrombosis and pulmonary embolism. 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. 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. Pneumonia can be life-threatening, most commonly in older patients with comorbidities or immunocompromised patients.

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. 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. 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. 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? 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.
