Pleural bronchogenic cysts: Imaging findings

Bronchogenic cysts occur most frequently in the middle mediastinum; almost all the remainder is present in the lungs. In this report, we describe 2 cases of bronchogenic cysts, which arose from the parietal and visceral pleura. Pathologically, each cyst showed an attachment with a small stalk to the parietal or visceral pleura. We suggest that bronchogenic cyst should be included in the differential diagnosis of cystic lesions in the pleural cavity.
