PET/CT Manifestations of a Case of Cavernous Hemangioma Misdiagnosed as Reproductive Tumor.

Cavernous hemangioma of mediastinum is a rare, benign tumor originating from vascular endothelial cells. It typically arises in the anterior mediastinum but has also been reported in the posterior mediastinum or the middle mediastinum, and occasionally involves both the anterior and middle compartments. We present the case of a 20-year-old man with a cavernous hemangioma of mediastinum initially misdiagnosed as a reproductive tumor by 18 F-FDG PET/CT.
