作者复习了10例儿童后颅窝室管膜瘤的 CT 表现,这些病例均经手术证实.男、女孩各5例,诊断时的平均年龄为6岁(10个月到15岁)。肿物9例位于第四脑室,一例累及脑干并有钙化,作者认为这是 CT 首次发现脑干室管膜瘤钙化的病例。10例中5例 CT 表现有钙化.小的钙化为结节灶;大的为极高的密度增加区.CT 扫描,在室管膜瘤未钙化区,呈密度增加者2例;等密度3例;低密度1例;混台型密度4例。10例中8例边界完整,7例边界不整齐。所有肿物均位于中线.对比剂强化后的 CT,2例显示均匀一致的强化
The authors reviewed the CT findings of the posterior fossa of 10 cases of children with pediatric ependymomas, all of which were confirmed by surgery, with 5 cases for each of the boys and girls. The median age at diagnosis was 6 years (10 months to 15 years). Nine cases of tumor located in the fourth ventricle, one case involving the brain stem and calcification, the authors believe that this is the first time that CT calcification of brain stem ependymoma cases. In 10 cases, 5 cases had calcification of CT, small calcification of nodules, and large area of extremely high density.CT scan showed increased density in 2 cases of ependymoma without calcification, 2 cases of equal density 3 Cases; low density in 1 case; mixing table density in 4 cases. Of the 10 cases, 8 had complete border and 7 had irregular border. All masses were in the midline. Contrast-enhanced CT showed 2 uniform enhancement
