Abstract STUDY DESIGN: Case report and review of the literature. OBJECTIVE: To report an unusual case of a spinal intradural extramedullary cavernous angioma (CA), located at the cauda equina, and to compare it with the previously published 22 surgically treated cases in the literature. SETTING: Ankara, Turkey. METHOD: A 67-year-old man presented with a 4-month history of back pain and sciatica and a 4-week history of progressive lower extremity paresthesia, difficulty walking, and loss of bladder and bowel sphincter control. Neurological examination revealed bilateral hypoesthesia below the T12 dermatome with spastic paraparesis. Magnetic resonance imaging (MRI) of the cauda equina revealed a heterogeneous enhancing intradural extramedullary mass obliterating the spinal canal and expanding the spinal cord. T12 laminectomy and total tumor removal were performed without additional neurological deficit. Pathological examination confirmed the diagnosis of a CA. RESULT: The patient's neurological status improved during postoperative recovery. He was ambulatory without assistance and regained full sphincter control on the eighth postoperative week. CONCLUSION: CAs of the spinal cord are extremely rare lesions. Typically, they present with low back pain and sciatica, neurological deficits, or as a subarachnoid hemorrhage. These lesions have characteristic features on MRI and should be considered in the differential diagnosis of intradural spinal lesions. Following a thorough literature review of reported cases, the authors propose that for patients presenting with severe preoperative neurological signs, immediate microsurgical tumor excision or decompression increases the chance of neurological improvement.
