A case of primary Intracranial Hypotension (PIH) is described. This syndrome consists of spontaneous lowering of CSF pressure with traction headache. It is a benign disorder and is self-limited. The cause is unknown, but local choroid plexus vasospasm, possibly due to a hypothalamic disturbance, has been suggested, as has leakage of CSF through spontaneous arachnoid tears. Transient symptomatic relief was achieved with 5% CO2 inhalation, apparently due to increase in cerebral blood flow.
本文描述了一例原发性颅内低压（PIH）病例。该综合征表现为脑脊液压力自发性降低并伴有牵引性头痛。它是一种良性疾病，具有自限性。病因不明，但有人提出可能是由于下丘脑功能紊乱导致局部脉络丛血管痉挛，也有人认为是脑脊液通过自发性蛛网膜裂孔漏出。吸入5%二氧化碳可实现短暂的症状缓解，这显然是由于脑血流量增加所致。
