Acute fibrinous organizing pneumonia (AFOP) is a rare, non-infective lung pathology histologically characterized by patchy distribution of intra-alveolar fibrin “balls” and organizing pneumonia. It needs to be differentiated from other forms of acute pneumonia like community acquired pneumonia (CAP) because the treatment modalities are contrastingly different. Interesting case of a 45-year-old male initially suspected as a case of acute bacterial pneumonia but finally diagnosed as case of AFOP, is being reported. Initial empirical antimicrobial therapy was ineffective, and the main treatment to which the patient responded was corticosteroids.
