Medulloblastoma is one of the common posterior fossa tumors in children. The natural history of this tumor in presymptomatic period is not well known. Widespread use of brain imaging has increased the detection of incidental brain tumors in totally asymptomatic persons. Here, we report a case of a 4-year-old boy with prenatal diagnosis of congenital brain abnormalities and neurofibromatosis type I. He underwent regular brain imaging to follow interhemispheric arachnoid cyst and ventriculomegaly that a posterior fossa tumor was discovered. The tumor size increased during time and became symptomatic after 28 months which was resected.
髓母细胞瘤是儿童常见的后颅窝肿瘤之一。该肿瘤在无症状期的自然病程尚不清楚。脑部影像学检查的广泛应用增加了在完全无症状人群中偶然发现脑肿瘤的几率。在此，我们报告一例4岁男孩，产前诊断为先天性脑异常和I型神经纤维瘤病。他接受了定期脑部影像学检查以监测大脑半球间蛛网膜囊肿和脑室扩大情况，在此期间发现了一个后颅窝肿瘤。肿瘤大小随时间增加，28个月后出现症状并接受了切除手术。
