We present a case of cerebellar tumoral multiple sclerosis in an 11-year-old girl and emphasize these two features: (1) Tumoral multiple sclerosis can occur within the posterior fossa and should be strongly considered in the differential diagnosis of mass lesions of the posterior fossa when typical white matter lesions are seen on T2-weighted images. (2) Tumoral multiple sclerosis can demonstrate ring enhancement on MR.
我们报告一例11岁女孩的小脑肿瘤型多发性硬化症,并强调以下两个特征:(1)肿瘤型多发性硬化症可发生于后颅窝,当T2加权图像上出现典型的白质病变时,在鉴别后颅窝肿块病变时应高度考虑此病。(2)肿瘤型多发性硬化症在磁共振成像上可表现为环形强化。
