摘要
目的:探讨外部性脑积水(EH)的CT征象。材料与方法:回顾性分析16例EH的临床CT资料。结果:双侧额或额顶部蛛网膜下腔对称性增宽(≥5mm)16例,纵裂前部增宽(≥6mm)16例,双侧裂池增宽16例,基底池扩大14例,额顶部脑沟增宽并加深13例。脑室轻度扩大6例。在1岁时复查16例外部性脑积水均有所减轻,2岁复查12例外部性脑积水完全消失;另4例进一步减轻,至3岁复查完全消失。结论:CT检查在EH诊断、鉴别诊断方面具有重要价值。
Purpose： To explore CT features of external hydrocephalus （EH）. Materials and Methods： The clinic and CT findings of 16 patients with EH were analyzed retrospectively. Results： Bilateral subraclmoid cavities in frontal and frontoperietal parts symmetrically broadened in 16 cases, 16 cases had wide front interhemispheric fissure. Every case was found wide bilateral fissure cistern. The basal cistern enlarged in 14 cases ventricles of brain slightly enlarged in 6 cases.
