The authors reported 7 cases of Dandy-Walker syndrome,all diagnosed by CT ex-amination,with 6 cases confirmed by operation and 2 cases followed by CT scan after operation. The main pathogenesis of Dandy-Walker syndrome is developmental abnormality of roof of the 4th ventri-cle. CT manifestations of this syndrome has common characteristics as follows:(1) Absence of cerebel-lar vermis;(2)4th ventricle extending posterosuperiorly from the missing vermis,with the shape of cyst, fan or triangle;(3)The cerebellar...

External hydrocephalus(EH) is a disease of non obstructive hydrocephalus which occurs in early infants. 28 cases were analysed by CT and clinically in this paper. The main appearance of EH are symmetrical widening of subarachnoid space at fronto parietal area, anterior part of longtudinal fissure cistern, enlargement of basal cistern,suprasellar cistern or lateral fissure cistern.These manifestations should be differentiated from cerebral atrophy and subdural fluid accumulation. The prognosis of majority of EH are good. Usually, it will be spontaneously cured by 2 to 3 years old. CT scanning has its specific manifestations and important value in the diagnosis of EH.

本文对28例外部性脑积水(Externalhydrocephalus,简称EH)患者进行临床和CT分析。EH主要CT表现为额顶区对称性蛛网膜下腔增宽,纵裂池前部增宽。基底池,鞍上池、外侧裂池可增大。EH在临床和CT表现方面须与脑萎缩,硬膜下积液鉴别诊断。EH多数预后良好,常在2~3岁自愈。其CT表现有特征性,在诊断EH中有重要价值
