MR was helpful in demonstrating the spatial relationship between a dermoid cyst in the fourth ventricle and an occipital dermal sinus. T1-weighted images clearly showed the mixed hypointense mass in the fourth ventricle and above the vermis, which appeared to be connected to an occipital dermal dimple.
磁共振成像(MR)有助于显示第四脑室内皮样囊肿与枕部皮样窦之间的空间关系。T1加权像清晰显示第四脑室内及蚓部上方的混合性低信号肿块,该肿块似乎与枕部皮肤凹陷相连。
