Cystic change (pseudocavitation) associated with bronchioloalveolar carcinoma: a report of four patients.
Cavitation in bronchioloalveolar carcinoma is uncommon, but apparent radiologic cavitation may be produced by other causes of abnormal air collections in and around the tumor. We report four patients whose plain films and computed tomography scans were interpreted as showing cavitary masses. Paracicatricial emphysema, fibrosis with honeycombing, and localized bronchiectasis were present pathologically to explain the abnormal air collections.
