Thoracic outlet syndrome secondary to a cavernous hemangioma of the first rib.

Bone hemangiomas are slow-growing benign tumors, with rib involvement being exceptionally rare. Thoracic outlet syndrome caused by a bone neoplasm of the first rib is even more uncommon, with only a few cases documented in the literature. We present the case of a patient with a clinical diagnosis of neurogenic thoracic outlet syndrome secondary to a bone tumor of the first rib, treated using a combined approach of video-assisted thoracoscopy and posterior access for resection. To our knowledge, this is the second reported case in the literature of a young man with thoracic outlet syndrome secondary to a cavernous hemangioma of the first rib.
