“…The course of postoperative recovery was uneventful, and Review of the literature Table 1 provides a summary of the 23 reported surgically treated cases of spinal intradural extramedullary CAs, including the present report. 1,[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] The ages of the patients are between 22 and 67 years, with an average of 43.3 year (Table 1). 65.2% of the patients presenting with intradural extramedullary spinal CAs are males.…”

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.

“…Cauda equina nerve root is a very rare location. 4,[9][10][11][12][13][15][16][17][18][19][21][22][23][24][25][26] Pagni et al 15 reviewed all intradural cavernous angioma of the spine described in the literature. They concluded that subdural extramedullary cavernous angiomas are the most rare of the cavernomas with only 10 cases documented between 1903 and 1990.…”

Study design: Case report and literature review. Objective: Intradural-extramedullary cavernoma is a rare condition with only 23 cases reported in the literature. Most cases described adhere to spinal root or spinal cord. We report an example of this rare entity located within the sheets of one cauda equina nerve root. Setting: Rome, Italy. Methods: The authors report clinical, radiological, surgical, and pathological features of intraroot cavernoma with a literature review. Results: Patient was operated. One year after surgery, he was healthy. Conclusion: Lumbar intradural cavernous angioma may present with sciatalgia, low-back pain, neurological deficit, or, more rarely with subarachnoid hemorrhage or hydrocephalus. They are treated successfully with surgical resection but preoperative status is a predicting factor for outcome. Sometimes the sacrifice of the spinal root is inevitable because, as in present case, the cavernous angioma is included in the nerve root. These lesions are rare and benign lesions. It is important for neurosurgeons to be aware of the existence of this entity to avoid preoperative misdiagnosis with tumor.

“…Of 14 cases of cavernous angioma occurring in cauda equina, which have been reported until now, six needed a surgical dissection of the nerve root 11) ( Table 1). Of these six cases, four developed such neurological symptoms as paresthesia or muscle weakness 7,10,14) . The remaining two did not develop neurological deficits even following the dissection of nerve root 10,11) .…”
