Abstract
Epidural cavernous angiomas are apparently rare lesions. We present an unusual case of chronic lumbar radiculopathy secondary to an epidural cavernous hemangioma extending into the intervertebral foramen. Few such reports have had the benefit of modern neuroimaging techniques to aid in preoperative diagnosis, and, therefore, magnetic resonance imaging of these lesions has not been extensively described. This article discusses the implications of the clinical presentation of the patient and reviews the characteristic magnetic resonance imaging appearance of this lesion garnered from this case and from a review of the literature.
