假脑瘤与“原发性空蝶鞍综合征”被认为是两个疾病分类学的范畴。前者为颅内压增加;气脑造影显示脑室系统及蛛网膜下腔正常。后者缺乏特征性的临床表现,其病理改变为扩张的蛛网膜下腔通过不完全的鞍膈进入蝶鞍。两者合并发生的报导很少,本文报告8例,均为肥胖妇女,年龄32～63岁。 Pseudotumor tumors and “primary voiding sella syndrome” are considered to be two categories of disease taxonomy. The former had an increase in intracranial pressure; the gas brain angiography showed normal ventricular system and subarachnoid space. The latter lacks the characteristic clinical manifestations and its pathological changes are that the expanded subarachnoid space enters the sella through an incomplete saddle. There are few reports of the merger of the two, this article reports 8 cases, all obese women, aged 32 to 63 years old.
