Thoracic extraosseous, epidural, cavernous hemangioma: Case report and review of literature

Abstract

A 40-year-old male presented with mid-thoracic backache and progressive, ascending, spastic, paraparesis for one year. Magnetic resonance imaging demonstrated an extraosseous, extradural mass, without any bone invasion at the T2-T4 vertebral levels, located dorsal to the thecal sac. The spinal cord was compressed ventrally. The lesion was totally excised after a T2-T4 laminectomy. Histopathological examination revealed a cavernous hemangioma. The authors reported this case and reviewed the literature, to explain why extraosseous, extradural, cavernous hemangiomas should be considered in the differential diagnosis of extradural thoracic compressive myelopathy.

Clinical characteristics and surgical outcomes of solitary spinal epidural cavernous angiomas

“…The characteristic features of capillary hemangioma are thin irregular capillary-sized vessels caught in low attenuating fibroses, lobular architecture and the presence of a lining of a continuous basal lamina (29). Typical histological features of CAs include large number of sinusoidal channels in collagenous tissue, sometimes with thrombosis, blood, calcification, and perivascular hemosiderin deposition (2,7,11,12). In the present study, all histological characteristics were consistent with CAs.…”

“…Solitary epidural CAs not originating from the vertebral bone are relatively rare. With the aid of magnetic resonance imaging (MRI), solitary epidural CAs are being discovered in increasing numbers; nevertheless, most previous studies are case reports with an associated literature review and large series studies are very limited in the literature (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17). Because of the risk of spontaneous and intraoperative bleeding, solitary epidural CAs need to get neurosurgeons more attention.…”

A Dumbbell-Shaped Extradural Intracanal Cavernous Hemangioma: A Rare Case Report and Review of Literature

“…Cavernous Hemangioma is a kind of tumor with dilated blood vessels and considered benign neoplasms [1][2][3]. They can be located anywhere in the neural axis as well as other part of the body like liver and eyes [3][4][5][6].…”

“…They can be located anywhere in the neural axis as well as other part of the body like liver and eyes [3][4][5][6]. Evidently, the most reported cases are intracranial and supratentorial [3].…”

“…They can be located anywhere in the neural axis as well as other part of the body like liver and eyes [3][4][5][6]. Evidently, the most reported cases are intracranial and supratentorial [3]. Also Spinal Cavernous Hemangiomas commonly occur in vertebral body extradurally and in some cases extend to spinal canal, which consist of only 'five'-12% of spinal vascular problems [1][2][3][4][5][6][7].…”
