分析髓母细胞瘤的CT表现以便更好地了解其典型CT特征。材料与方法：本文搜集27倒随母细胞瘤，其中23例行CT平扫和增强扫描。结果：大多数（81．5％）病变在CT平扫时呈非均质性、稍高密度或等密度肿块，内有些低密度灶。增强扫描时，通常（85.2％）呈非均匀性强化，其内的坏死低密度灶更为明显。结论：大多数髓母细胞瘤的典型CT表现并不是均质性的，而是非均质性的，内有低密度区。本组CT表现不同于其他许多人的报告，因此该CT特征在小脑肿块的鉴别诊断中或许有一定的帮助。
The CT findings of medulloblastoma were analyzed in order to better understand its typical CT features. Materials and Methods: This article collected 27 inverted neuroblastoma, of which 23 cases of plain CT scan and enhanced scan. Results: The majority of lesions (81.5%) were heterogeneous in CT scan, slightly higher density or isodense mass, with some low density lesions. Enhanced scan, usually (85.2%) was heterogeneous enhancement, the necrosis of the low-density lesions within the more obvious. CONCLUSIONS: The typical CT findings of most medulloblasts are not homogeneous, but heterogeneous, with low density areas. This group of CT performance is different from many other reports, so the CT features in the differential diagnosis of cerebellar masses may have some help.
