Dumbbell-shaped spinal extradural hemangioma.

A case of recurrent extradural cavernous hemangioma is presented. In contrast to secondary extension of a vertebral hemangioma to the epidural space, pure epidural hemangioma is rare. The location of this case was at the level of the 7th thoracic vertebra, and the tumor showed unusual dumbbell-like growth through an intervertebral foramen. The rarity of these lesions, as well as their clinical and radiological features, the diagnostic procedure, and the treatment are discussed.
