成髓细胞瘤常好发于儿童小脑蚓部近中线处,占小儿中枢神经肿瘤的15％～25％,而只占成人颅内肿瘤的1％,成人的成髓细胞瘤发生于小脑半球的多于蚓部,组织学上可表现出促结缔组织生成的特性。 作者报道了15例经病理证实的小脑成髓细胞瘤的神经影象学和临床资料。年龄18～53岁,男9例,女6例,均经CT和MR检查,并着重观察肿瘤的大小、形态、位置、肿瘤的范围以及与小脑幕、硬脑膜的关系、周围水肿的程度、肿瘤内部有无囊变、出血和坏 Myeloblastosis often occurs in children near the midbrain cerebellar vermis, accounting for 15% to 25% of children with central nervous system tumors, and only accounts for 1% of adult intracranial tumors, adult myeloblastosis occurred in the cerebellar hemispheres More than in the vermis, histology can be shown to promote the formation of connective tissue properties. The authors reported neuropathological and clinical data of 15 pathologically confirmed cerebellar myeloblastomas. Aged 18-53 years, 9 males and 6 females, all underwent CT and MR examinations. The size, shape, location, tumor size, the relationship with the cerebellar tentorium and dura mater, the degree of surrounding edema, Whether there is cystic degeneration within the tumor, bleeding and bad
