A case of intradural extramedullary cavernous angioma is presented with headache, dizziness, and bilateral sensorineural hearing loss caused by an intracranial superficial hemosiderosis. It was incidentally found in a patient with a 3-month history of sustained headache, dizziness and a 3-year history of hearing difficulty. The neurological examination was unremarkable in the lower extremity. MR images showed an intracranial superficial hemosiderosis mostly in the cerebellar region. Myelography and MR images of the thoracolumbar spine revealed an intradural extramedullary mass, which was pathologically proven to be a cavernous angioma. T12 total laminoplastic laminotomy and total tumor removal were performed without any neurologic deficits. The patient's symptoms, including headache and dizziness, have been absent for three years. Intradural extramedullary cavernous angioma can present with an intracranial superficial hemosiderosis as a result of chronic subarachnoid hemorrhage.
本文报告一例硬脊膜内髓外海绵状血管瘤病例，该患者因颅内表面铁沉积症出现头痛、头晕及双侧感音神经性听力损失。此病例偶然发现于一名有3个月持续性头痛、头晕病史及3年听力困难病史的患者。下肢神经系统检查未见异常。磁共振成像（MR）显示颅内表面铁沉积症主要位于小脑区域。胸腰椎脊髓造影及MR图像显示硬脊膜内髓外肿块，病理证实为海绵状血管瘤。行T12全椎板成形椎板切开术及肿瘤全切术，术后无任何神经功能缺损。患者头痛、头晕等症状已消失3年。硬脊膜内髓外海绵状血管瘤可因慢性蛛网膜下腔出血导致颅内表面铁沉积症。
