Aspergillosis is an uncommon complication of pulmonary carcinoma. A 60-year-old female was performed right lower lobectomy because of adenocarcinoma with pseudocavities. The diagnosis was bronchiolo-alveolar adenocarcinoma, and there was aspergilloma in one of the cysts in the tumor. Cavitation or cystic change in bronchiolo-alveolar adenocarcinoma is rare because of nondestructive growth pattern with an adequate blood supply in this histologic type. Additionally, bronchiolo-alveolar adenocarcinoma associated with pulmonary aspergilloma is rare.
