Numerous migrational abnormalities can be seen in children presenting with seizures or developmental delay which depend on the time of insult and includes various anomalies including cortical malformation,schizecephaly, and heterotopia.CT has very low sensitivity in detecting these abnormalities.MRI is the investigation of choice due to its excellent soft-tissue resolution,grey-white matter differentiation, and multiplanar capability. The radiologist must prepare an algorithm for diagnosis to avoid missing these lesions and guide the clinician in the appropriate management.
