[A rare tumor of the mediastinum: benign hemangioma]

Mediastinal hemangiomas are rare tumours occurring more often in children and young adults. A new case is reported in a 21 years old male who had an anterior mediastinal mass detected on a routine chest roentgenogram. Pre-operative investigations including CT, venous digital angiography, MRI did not aid in the right diagnosis. The mass was totally removed surgically although involving extensively adjacent structures. Histologic examination of the tumour showed it to be a benign venous hemangioma. Clinical, radiological, pathologic features of mediastinal hemangiomas are reviewed and discussed.
