title: Posterior mediastinal hemangioma.
abstract: We report posterior mediastinal hemangiomas in a 4-month-old and a 6-month-old girl. The masses were identified on radiographs of the chest followed by contrast-enhanced CT. Histological evaluation of the surgical specimens established the final diagnosis. Although mediastinal hemangiomas have been described, they remain a rare entity. A diagnosis can be suggested by relatively high attenuating masses on contrast-enhanced CT. Posterior mediastinal hemangiomas sometimes mimic neuroblastomas, which is the most common posterior mediastinal in this age group.
