Abstract
Cavernous malformations, also termed “cavernous hemangiomas,” “cavernous angiomas,” and “cavernomas”, terms that may carry different histological variations, are benign developmental anomalies composed of endothelium lined vascular channels. They are found throughout the Central Nervous System, but rarely occur in the spine. Spinal cavernous hemangiomas are vascular malformations with a reported incidence of 5% to 12% of all spinal vascular abnormalities. Approximately 3% of spinal cavernous hemangiomas are intradural, usually with an intramedullary location. Epidural cavernous hemangioma of the spine, account for approximately 4% of these vascular epidural lesions.

Cavernous malformations, termed “cavernous hemangiomas,” “cavernous angiomas,” and “cavernomas”, terms that may carry different histological variations, are benign developmental anomalies composed of endothelium lined vascular channels
Cavernous hemangiomas, which are otherwise known as cavernomas, this term may confer
A cavernous hemangioma consists of irregular vascular spaces which are lined by a single layer of endothelium
Summary
Termed “cavernous hemangiomas,” “cavernous angiomas,” and “cavernomas”, terms that may carry different histological variations, are benign developmental anomalies composed of endothelium lined vascular channels They are found throughout the Central Nervous System, but rarely occur in the spine [1]. Prior to 1990 only 10 surgically treated cases were reported in the literature [3], by 2003 this number had increased [4] with few cases located in the cervical and thoracolumbar spine [5,6] Due to their rareness, the variable clinical symptoms and variable MR findings, diagnosis of these lesions is often difficult [5]. The patient is currently followed closely for hemangioma recurrence and spinal deformities, and genetic investigation is underway
