Acute fibrinous and organizing pneumonia

Abstract

Acute fibrinous and organizing pneumonia (AFOP) is a very rare form of acute or subacute lung injury, which is characterized by patches of fibrin deposits within the alveoli. There are no typical clinical features, and hence, it is often misdiagnosed as pneumonia, tuberculosis, or acute lung injury. A definitive diagnosis is obtained from a lung biopsy. AFOP responds to corticosteroids. Here, we present a case of AFOP and discuss the clinical manifestations, radiological findings, and management.
