Abstract

Acute interstitial pneumonia (AIP) is a descriptive term for a specific histopathological pattern, including hyaline membrane formation, and proliferation of type II alveolar epithelial cells.6,18 Other lesions often identified are interlobular edema, hemorrhage and vascular congestion. The condition occurs secondary to alveolar wall damage resulting in transudation of relatively acellular, and fibrinogen-rich fluid into alveolar spaces and terminal airways.
