Cavernous angiomas are common lesions of the CNS characterized by abnormally dilated blood vessels lined by a thin endothelium, closely clustered together and not separated by normal neural tissue. They are more frequently found intracranially. In the spine, a common location is the vertebral bodies. Intradural extramedullary and intramedullary cavernous angiomas are less frequent lesions, while purely epidural locations are uncommon. Spinal dumbbell-shaped epidural cavernous angiomas are exceedingly rare, and only six cases have been reported in the literature. We describe one additional case whose MRI appearance was indistinguishable from that of a neurinoma, which is a much more common lesion. Surgical treatment is advised and complete radiological evaluation is necessary to rule out concomitant localizations in other organs.

Abstract
Cavernous angiomas are common lesions of the CNS characterized by abnormally dilated blood vessels lined by a thin endothelium, closely clustered together and not separated by normal neural tissue. They are more frequently found intracranially. In the spine, a common location is the vertebral bodies. Intradural extramedullary and intramedullary cavernous angiomas are less frequent lesions, while purely epidural locations are uncommon. Spinal dumbbell-shaped epidural cavernous angiomas are exceedingly rare, and only six cases have been reported in the literature. We describe one additional case whose MRI appearance was indistinguishable from that of a neurinoma, which is a much more common lesion. Surgical treatment is advised and complete radiological evaluation is necessary to rule out concomitant localizations in other organs.
