report of a case: an intradural between roots capillary hemangioma of cauda equina

Background & importance: cavernous angiomas are typically superficial lesionscreated by anomalous vessels and found in the skin or mucosa, but intradural locations are rare especially in the spine. we report a case of the spinal intradural cavernous angiomas of the lumbar spine. case presentation: a 53-year-old man presented with a 6-month history of low back pain and bilateral radicular pain. in examinations, the patient was shown to have numbness in the anterior aspect of the right thigh in l2 territoryand a decrease in lower limb tendon reflexes. magnetic resonance imaging (mri) revealed at l1-l2 level, a well-defined intradural lesion in conusmedularis measuring about 18*12mm that shows high signal intensity in t1 images and low signal intensity in t2 images, which causes compression on the cauda roots. laminectomy of l1-2 was performedfor tumor removal and intradural exploration revealed a small oval shape, brownish cystic like mass surrounded by adherent nerve roots. complete removal of this tumor was accomplished. histologic diagnosis wascapillary hemangioma. after operation, the patient’s symptoms were improved. conclusion: we experienced and reported a rare spinal intradural vascular tumor of the lumbar spine. histologicdiagnosis was cavernous angiomas.
