Abstract
We report a rare case of mediastinal lymphangioma. A 33-year-old female was pointed out as having a mediastinal tumor on chest radiograph. She had a varied previous medical history: cardiac tamponade, multiple liver cysts, and cerebral arteriovenous malformation. Computed tomography showed a large anterior mediastinal tumor involving the aorta and pulmonary artery, Since needle biopsy failed to facilitate a definitive diagnosis, surgical removal of the tumor was performed. Histopathological examination resulted in a diagnosis of lymphangioma, which is very rare in adults.
