外部性脑积水的CT诊断及临床治疗价值分析

CT Diagnosis of the External Hydrocephalus

    摘要
  • 摘要: 目的: 探讨外部性脑积水的CT特征及临床应用价值。方法: 分析63例外部性脑积水的CT表现及测量脑室及颅腔横径(VT/ST)率。结果: EH的CT特征为:额顶区蛛网膜下隙对称性增宽(≥5mm),前纵裂池增宽(≥6mm),可有脑沟增宽,额顶叶边缘呈"花瓣状",可伴有双侧侧裂池及鞍上池扩大,脑室轻度扩大或不扩大,VT/ST率小于15%。27例随访病例均有好转。结论: 依据CT特征,结合患儿头围增大,前囟膨隆及抽搐,对EH进行诊断,CT检查对EH的临床诊断及指导治疗具有重要价值。

     

    Abstract: Objective: To evaluate CT diagnosis and clinical application in external hydrocephalus(EH).Methods: The CT features of 63 cases of EH were retrospectively analyzed.The ratio of the transverse diameter of the ventricle and skull was measured in all the cases.Results: The characteristic CT features of EH were as follows:(1) Widening of the interhemispheric fissure,Widening of the subarachnoid space in the bifrontoparietal regions;(2) Widening and deepening of the sulcus in the bifrontoparietal regions in some cases,edge like petal;(3) Widening and enlargement of the cistern of bilateral fossae and suprasellae cistern in some cases;(4) little or slight enlargement of the cerebral ventricles and(5) The ratio VT/ST was smaller than 15%.Conclusion: Combining the characteristic CT features with the clinical findings such as enlargement of the head circumference,expansion of the anterior fontanel,seizures of convulsion,etc,a physician is diagnose EH.CT plays an important role in the diagnosis and management of the patients with EH.
