Cavernous destruction of an upper lung lobe in a healthy young man. An unusual roentgenographic presentation of allergic bronchopulmonary aspergillosis.

We describe a 32-year-old man with no history of pulmonary disease who presented with extensive cavernous destruction of the right upper lobe as an incidental finding on a chest x-ray film. All major criteria of allergic bronchopulmonary aspergillosis (ABPA) were present. Histologic examination of the resected lobe showed the typical features of ABPA. The differential diagnosis of multiple cavitating lesions should include ABPA.
