Hemimegalencephaly is a malformation of cortical development that normally manifests in childhood with seizures and cognitive impairment. We present a case of hemimegalencephaly in a 55‐year‐old developmentally‐normal woman who developed focal impaired awareness seizures with bilateral tonic‐clonic spread. Her interictal EEG showed left‐sided multifocal spikes, and ictal EEG showed seizures starting in the left hemisphere. Imaging showed hemimegalencephaly. This case may represent the oldest age for a first seizure in a patient with hemimegalencephaly.
