Abstract:
A 54-year-old asymptomatic man presented with an anterior mediastinal mass discovered on chest roentgenogram. Chest computed tomography revealed a noncalcified round mass in the mediastinum. A white solid mass, 5-cm in diameter, had arisen from the pericardial adipose tissue with multiple small nodular lesions mimicking mediastinal tumor with pleural dissemination. Postoperative pathologic examination confirmed a diagnosis of sclerosing mediastinitis. Details of the clinical and radiographic feature are presented.
