A case with a presumptive diagnosis of a functional sylvian aqueductal stenosis is presented. The patient was a 64-year-old female, who suffered from progressive gait disturbance and dementia. On admission, CT-scan showed lateral and third ventricular dilatations. The pattern of the ventricular dilatation suggested an aqueductal stenosis. But CT-scan showed no tumorous lesion. RI-cisternography, RI-ventriculography, aqueductgraphy, and continuous monitoring of the intraventricular pressure of the third ventricle were performed in order to make a diagnosis. The results of these examinations led to the following conclusion. "Although there was no apparent mechanical obstruction or stenosis, the presence of circulatory failure of CSF, demonstrated apparent functional stenosis of the aqueduct sylvii." A VP-shunt operation was performed a month after her admission. Her symptoms improved remarkably.
本文报告一例初步诊断为功能性中脑导水管狭窄的病例。患者为64岁女性，患有进行性步态障碍和痴呆。入院时，CT扫描显示侧脑室和第三脑室扩张。脑室扩张的模式提示导水管狭窄。但CT扫描未显示肿瘤性病变。为了做出诊断，进行了放射性核素脑池造影、放射性核素脑室造影、导水管造影以及对第三脑室室内压力的连续监测。这些检查结果得出以下结论：“虽然没有明显的机械性梗阻或狭窄，但脑脊液循环衰竭的存在表明中脑导水管存在明显的功能性狭窄。”患者入院一个月后进行了脑室腹腔分流术。她的症状明显改善。
