On T1-WIs and T2-WIs,these lesions appeared isointense to the normal gray matter. 2 lesions associated with arachnoid cyst,2 lesions with schizencephaly and 1 lesion with dysgenesis of the corpus callosum and lipoma of midline. During contrast on MRI(n=5) ,all lesions show unenhancement. Conclusion The MRI have characteristics in diagnosis of heterotopic gray matter and is the best method.
