本文分析了３４例≤２０岁患者的脑胶质瘤ＣＴ表现。与＞２０岁患者的胶质瘤比较，≤２０岁病例占同时总病例的比例（１８．９％）很小。肿瘤多位于幕下和幕上中线部位（７３．５％），ＣＴ表现以良性特点居多数。这些特征在０～１５岁尤为突出，而在１６～２０岁组则接近＞２０岁胶质瘤的常见ＣＴ类型。比较２３例有分级者ＣＴ表现与病理级别的关系，发现单项、甚至多项指标也不能可靠地反映肿瘤的分化程度。本文试用的ＣＴ分级与病理分级显示不相关，还简要地分析了不相关的原因。
This article analyzes 34 cases of patients ≤ 20 years of glioma CT manifestations. Compared with glioma patients> 20 years of age, the proportion of patients aged ≤20 years at the same time (18.9%) was very small. Tumors are mostly located in the infratentorial and supratentorial parts (73.5%), and CT is characterized by benign features. These features are particularly prominent at 0 to 15 years of age, whereas those in the age group of 16 to 20 years are close to common CT types of> 20 years old gliomas. Comparison of 23 cases with grading CT showed the relationship between the pathological level and found that even single or even multiple indicators can not reliably reflect the degree of tumor differentiation. This trial of CT grade and pathological grade showed no correlation, but also briefly analyzed the reasons unrelated.
