title: Massive mediastinal teratoma mimicking a pleural effusion on computed tomography.
abstract: Mediastinal teratomas have been reported to mimic pleural effusions on chest radiography. Further evaluation of such tumours using computed tomography usually yields diagnostic characteristics that distinguish them from pleural collections. We report a patient with a mediastinal teratoma that mimicked a massive left pleural effusion on chest radiography and computed tomography.
