目的评价脑胶质肉瘤的CT诊断价值。方法回顾性分析5例经手术病理证实的脑胶质肉瘤的CT表现,并复习文献。结果肿瘤均位于幕上,其中颞叶3例,额颞叶1例,枕顶叶1例。CT扫描4例为低等混杂密度,1例为稍高密度,增强扫描为不规则强化。边界清楚,4例周围有水肿,1例无周围水肿。结论脑胶质肉瘤少见,CT扫描能够清楚显示病变,但易与胶质母细胞瘤、转移瘤等相混淆,确诊依靠病理检查。
Objective To evaluate the diagnostic value of glioma in CT. Methods A retrospective analysis of 5 cases of pathologically confirmed glioma sarcoma CT performance and review of the literature. Results The tumors were located on the screen, including 3 cases of temporal lobe, 1 case of frontotemporal lobe and 1 case of occipital parietal lobe. 4 cases of CT scan for the low hybrid density, a slightly higher density, enhanced scan enhanced irregular. Clear border, 4 cases of edema around, 1 case of no peripheral edema.
