Pulmonary Infection in Healthy and Immunocompromised Patients

Pneumonias are ideally classified according to the infecting organisms because the cause dictates the treatment. However, imaging is very variable and frequently poor at predicting the category of infectious agent. The role of imaging in patients with pulmonary infections is three-fold and includes detection, characterization and diagnosis of complications. Typical radiographic findings of bronchopneumonia, lobar, and interstitial pneumonia and their underlying spectrum of infectious agents will be outlined. Complications of pneumonias such as abscess formation, cavitation, empyema or formation of a broncho-pleu…
