Extradural Lumbosacral Cavernous Hemangioma

Abstract

Purely extradural cavernous hemangiomas of the spinal canal are extremely rare. Their occurrence at the lumbosacral level is a true exception. We describe a case of lumbosacral extradural hemangioma and review the behaviour and MR imaging characteristics of these lesions. Cavernous hemangioma should be considered in the differential diagnosis of an enhancing extradural periradicular mass causing chronic lumbar radiculopathy especially in fertile women. Lumbar extradural hemangiomas appear and behave differently, not only from intramedullary cavernous hemangiomas but also from extradural hemangiomas of other spinal locations.
