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.

Solitary spinal epidural cavernous angioma: report of nine surgically treated cases and review of the literature

“…Bleeding is seldom a problem with intramedullary cavernous angiomas during surgery, however, severe intraoperative bleeding may occur in spinal epidural cavernous angiomas [17]. Therefore, adequate exposure is necessary to prevent massive intraoperative bleeding, especially in the lumbar lesions, where the lesion resembles a disc fragment [26,28]. In our series, complete surgical removal was achieved in all cases and confirmed by postoperative MRI.…”

“…They are usually confined to two or more spinal levels, and have an oval shape, sometimes flattened toward the spinal cord rather than distorting it [15,25]. SSECA are well delineated and often have a capsule or pseudo-capsule [3,26]. Lesions of the lumbosacral region are usually round or ovoid, located in the ventral and/or ventro-lateral epidural space or just within the peri-radicular space [9,26,28] as in our case 3 and 8.…”

Pure Spinal Epidural Cavernous Hemangioma: A Case Report

“…It is very difficult to diagnose before surgery. A study by Tekkök et al 13) reported on 14 surgical resections of cavernous hemangioma, none of which was diagnosed preoperatively.…”

Lumbar extradural dumbbell cavernous hemangioma: A rare lesion

“…Lumbar extradural hemangiomas behave differently, not only from intramedullary cavernous hemangiomas but also from extradural cavernomas of other spinal locations. [9] Purely extradural hemangiomas should be included in the differential diagnosis of lumbar extradural soft-tissue lesions. [10]…”
