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.
