We report a female infant with status epilepticus amauroticus and intractable focal motor seizures associated with congenital cortical dysplasia. EEG demonstrated persistent epileptiform discharges over the right parieto‐temporal regions extending to occipital areas. She required cortical resection of the epileptic zone at age 8 months given failure of very high dose antiepileptic combinations. Histological analysis of a sample of cortex resected from the right central parieto‐temporal region, identified by electrocorticography as the focus of epileptic activity, showed cortical dysplasia. The seizures ceased and the infant gained full vision after 48 hours. During an 8‐year follow‐up period she has had a few short‐lived seizures, currently controlled with carbamazepine and vigabatrin. Her cognition and speech are intact. This case demonstrates that: (1) resection of a central temporo‐parietal focus, which may have spread to the occipital regions, may result in complete visual recovery and cessation of seizures; and (2) EEG should be considered in every infant with alleged delayed visual maturation, to rule out concealed epileptic activity.
