摘要
本文报道４例脑灰质异位病例。脑灰质异位较为少见，病变常发发生于白质区及侧脑室周围，在Ｔ１加权、质子密度、Ｔ２加权像上病变与灰质信号相同。该病易发生癫痫，需与肿瘤及结节性硬化鉴别，ＭＲＩ能对该病作出明确诊断。
cases of heterotopic cerebral gray matter were reported. Heterotopic cerebral gray matter is a rare disease. The lesions often located in periventrcular or within the white matter,They had a signal intensity that was isointense compared with that of gray matter on T1,spin-density,and T2-weighted images. Seizures were the common symtoms of the disease. Heterotopic gray matter may be differentiated with r and tuberous sclercasis, It can be clearly diagnosised with MRI.
