Heterotopy of the gray matter is a very rare cause of epilepsy in children. It is a disorder of neuronal migration during embryonic life, responsible for the presence of neurons outside the cortex. Gray matter heterotopias are common forms of cortical developmental malformations characterized by the presence of cortical neurons in abnormal positions. They are caused by the arrest of migration of neurons from the germinal matrix in the wall of the lateral ventricle to the developing cerebral cortex between the 6th and 16th week of gestation. It is usually discovered during the evaluation of children or young adults with refractory epilepsy. In Our study we report a series of 08 patients collected in our hospital within a period of 6 years from 2016 to 2022, diagnosed with heterotopia of the grey matter, however, six patients had benefited from an MRI and two from a CT scan...
