Dumbbell-shaped spinal epidural cavernous angioma. Case report.
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.
