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

Abstract

Cavernous hemangiomas, first described by Globus in 1929, are one of the uncommon vascular malformations of central nervous system. They seemed to have benign vascular structure with dilated vessel bed. Cavernous hemangiomas encompass nearly 'five'-12% of all spinal vascular malformations; however, existence in the epidural space without bone involvement is rare. Only 'four'% of all cavernous hemangiomas are merely epidural cavernous hemangiomas. In this case report, we removed a hemorrhagic thoracic mass by T3-T5 laminectomy presenting with neurological deficits mimicking symptoms of intervertebral disk herniation in a 33-year-old male patient who came to our Clinic. We have chosen this case to be reported due to its rare characteristics and occurrence of this type of cavernous hemangioma in the world.

Spinal epidural Cavernous Hemangioma mimicking Schwannoma: Case report and review of literature

“…Spinal cavernous hemangiomas usually originate from the vertebral body and may present in the epidural space through secondary extension. Pure epidural cavernous hemangiomas are a rare entity and they account for 12% of all intraspinal cavernous malformations and only 4% of all spinal epidural tumors 2,4,5,7,8,9,11,12,13 . Most literature on pure spinal epidural cavernous hemangiomas is based on isolated case reports and small case series [2][3][4][5][6][7][8][9][10][11][12][13] .…”

“…They usually present in patients aged 30-60 years with peak incidence at 40 years of age 3,4,5 . Literature review has revealed a female preponderance in most reports 2,3,4 . However, there are conflicting reports showing a predominantly male distribution 3,11,12 .…”

“…Cavernous Hemangioma must be considered in the differential diagnosis of pure extradural spinal lesions. These tumors are generally benign slow growing lesions which usually present with features of myelopathy 2,3,4,5 . These lesions are usually an extension from a vertebral origin, but less commonly, they are purely extradural and may be misdiagnosed pre-operatively as nerve sheath tumors and meningiomas 2,6,7 .…”
