Aortic coarctation in the presence of capillary hemangioma.

We report posterior mediastinal hemangioma in a 14-year-old girl patient with an extensive hemangioma encompassing the thoracic aorta, associated with complex coarctation. The masses were identified by contrast-enhanced computed tomography. An extra-anatomical bypass was made by grafting from the ascending to the distal descending aorta. Histological evaluation of the surgical specimens established the final diagnosis. Presence of mediastinal hemangiomas should be regarded as an important differential diagnosis of coarctation of aorta, although these are very rare tumors.
