Intracranial hypotension is a rare, and possibly underrecognized, cause of headache in middle age. Occurring spontaneously in the vast majority of cases, it has been occasionally reported after certain neurosurgical procedures involving craniectomy. We report a unique situation in which a patient developed severe postural headache typical of intracranial hypotension, which was complicated by bilateral subdural hematomas, immediately following a routine lumbar diskectomy; the headache resolved spontaneously. We suggest that an intraoperative microscopic dural breach was the site of sustained, but self-limited, cerebrospinal fluid leakage that eventually led to intracranial hypotension.
颅内低压是中年人群中一种罕见且可能未被充分认识的头痛原因。绝大多数情况下为自发性发生，偶尔也有报道在某些涉及颅骨切除术的神经外科手术后出现。我们报告了一种独特的情况，一名患者在常规腰椎间盘切除术后立即出现了典型的颅内低压性严重体位性头痛，并伴有双侧硬膜下血肿；头痛随后自行缓解。我们认为术中显微镜下硬膜破裂是脑脊液持续但自限性漏出的部位，最终导致了颅内低压。
