Rapidly expanding extrapleural hematoma.

We present a rare case of extrapleural hematoma due to chest trauma in an anticoagulated male patient. Chest computed tomography revealed multiple left rib fractures and a D-shaped opacity in the upper left side of the thorax suggesting extrapleural hematoma, which was caused from continuous bleeding. His past history included alcoholic liver cirrhosis, which caused thrombocytopenia and coagulopathy.

Pediculate mucinous cystadenoma difficult to differentiate from pleural tumor.

We present a case of benign pediculate mucinous cystadenoma in a 60-year-old man. The tumor, which was connected with the lung parenchyma, was difficult to distinguish from a pleural tumor radiographically. Initially, computed tomographic-guided needle aspiration biopsy was performed to confirm the diagnosis, but this was unsuccessful.
