Spontaneous intracranial hypotension is frequently idiopathic. The authors report on a patient presenting with symptomatic intracranial hypotension caused by a transdural calcified thoracic disc herniation. Cranial magnetic resonance (MR) imaging revealed classic signs of intracranial hypotension, and a combination of spinal MR and computerized tomography myelography confirmed a mid-thoracic transdural calcified herniated disc as the cause. The patient was treated with an epidural blood patch and burr hole drainage of the subdural effusion on two occasions. Postoperatively the headache resolved and there was no neurological deficit. Thoracic disc herniation may be a cause of spontaneous intracranial hypotension.
自发性颅内低压常常病因不明。作者报告了一例因经硬脊膜钙化的胸椎间盘突出导致症状性颅内低压的患者。头颅磁共振成像显示出颅内低压的典型征象，脊柱磁共振成像与计算机断层脊髓造影相结合证实胸段中部经硬脊膜钙化的椎间盘突出为病因。该患者接受了两次硬膜外血贴及硬膜下积液钻孔引流治疗。术后头痛缓解，且无神经功能缺损。胸椎间盘突出可能是自发性颅内低压的一个病因。
