AIM:To evaluate magnetic resonance imaging(MRI) features of different types of gray matter heterotopia.METHODS:Between June 2005 and December 2009,the medical records and MRI studies of patients with gray matter heterotopia were reviewed.The MRI morphologic findings of heterotopia were recorded along with the presence and type of associated cranial malformations.Available clinical and electrophysiological data were also recorded.RESULTS:20 patients were included in the study.Their ages ranged from 9 mo to 39 years with a mean age of 15 years.All patients suffered from epileptic seizures.According to the location of heterotopia,patients were classified into three groups:subependymal(12),subcortical(5) and band(3) heterotopia.CONCLUSION:MRI was useful in diagnosing and differentiating between various types of gray matter heterotopia.The severity of clinical manifestations of heterotopia was related to the location and pattern of heterotopia.Determination of heterotopia type and its extent is useful for management planning and predicting prognosis.
