Difficulty in detecting small acoustic neuromas has encouraged us to study patients suspected of having a tumor by air cisternography augmented with computed tomography. Ninety patients were examined without complication. Five cubic centimeter of air was introduced via lumbar puncture and manipulated into the cerebellopontine angle cisterns. Scanning is commenced immediately. Filling of both internal auditory canals and identification of the neurovascular bundle in the cerebellopontine angle cistern was possible in all patients except those with tumors. The diagnostic accuracy, speed, and lack of morbidity have made this procedure the initial radiologic examination at our institution for patients suspected of having acoustic neuroma.
小听神经瘤检测困难，促使我们对疑似患有肿瘤的患者进行研究，采用计算机断层扫描增强气脑池造影术。90例患者接受了检查，无并发症发生。通过腰椎穿刺注入5立方厘米空气，并将其导入桥小脑角池。立即开始扫描。除肿瘤患者外，所有患者均能使双侧内耳道充盈，并识别桥小脑角池内的神经血管束。该检查的诊断准确性、速度及无发病率使其成为我们机构对疑似听神经瘤患者进行的初步影像学检查。
