单侧脑室扩大的病因及CT表现分析

摘要

目的：探讨单侧脑室扩大的病因及CT表现。方法回顾性分析108例单侧脑室扩大的病因及CT表现。结果单侧脑室扩大可见于先天性及后天性疾病或原因不明。原发病变包括一侧脑室扩大变异64例， Dyke-Davidoff-Masson综合征6例，脑梗死12例，脑出血15例，脑室积血4例，脑转移瘤2例，Sturge-Weber综合征3例，胼胝体发育不全2例。结论单侧脑室扩大的病因多样，影像学检查对探及病因有一定的作用。%Objective To explore causes and CT findings of ipsilateral ventricular dilatation. Methods One hundred and eight cases of diseased samples were studied by CT technology, and the images generated were analyzed to establish the causes of ipsilateral ventricular dilatation. Results Ipsilateral ventricular dilatation was observed in congenital disease and acquired disease or unknown origin. Primary diseases of ipsilateral ventricular dilatation in-cluded: ventricle variation (n=64), Dyke-Davidoff-Masson syndrome (n=6), cerebral infarction (n=12), cerebral hemor-rhage(n=15), intraventricular hemorrhage(n=4), brain metastases(n=2), Sturge-Weber syndrome(n=3) and dysgenesis of the corpus callosum (n=2). Conclusion Etiologies of ipsilateral ventricular dilatation are varied. The findings from this research suggest that CT images can be used to identify, and detect, the etiology of ipsilateral ventricular dilata-tion.
