摘要
脑干肿瘤儿童常见,大多数为胶质瘤。本文对60例儿童脑干肿瘤进行了CT 研究,CT 表现因肿瘤的生物学特性而异。浸润性肿瘤脑干弥漫性肿大,呈低或等密度灶,部分性对比增强;慢性生长肿瘤可见脑干内肿块,并向脑干外突出,密度均匀或不均,且有明显的强化。脑干肿瘤CT 诊断基于第四脑室的受压移位,和脑干周围脑池的狭窄变形。
Brain stem tumors are relatively frequent in children.The most of them are brain stemgliomas.In 60 cases of CT studies in children with brain stem tumors,the CT appearance was seen tovary with the tumor's biological characteristics.Infiltrative gliomas produce diffuse enlargement of thebrain stem;they are decreaed density or isodense with brain parenchyma and may show partialenhancement.Some grow focally as an expansile mass or a large exotic lesion.These have heterogeneousdensity and show prominent enhancement.CT diagnosis based on appreciation of displacement of thefouth ventricle and compression and distortion of the cisterns that around the brain stem.
