Pulmonary bullae usually grow slowly and have thin walls.However, we have observed 2 cases of abrupt bulla formation immediately after lobectomy and during surgery.The pathologic findings of what can be called visceral pleural detachment are quite distinctive: these bullae F-type had a broad base connected to the lung, and their walls were thick, including the full extent of visceral pleural Roasting Rack and peripheral alveolar tissues, which suggests that the visceral pleura were detached from the distal alveoli.
