SummaryFocal cortical dyplasia (FCD) is a frequent cause of medication‐resistant focal epilepsy. Patients with FCD may benefit from epilepsy surgery. However, it is difficult to intraoperatively define lesion boundaries. In this case report we present a novel tool to identify FCD intraoperatively. A patient with frontal lobe epilepsy underwent resection of a left frontomesial FCD. Image guidance was achieved by intraoperative ultrasound, which depicted the lesion with a higher resolution than preoperative MRI. Postoperatively the patient remained seizure free. Intraoperative ultrasound may be helpful in identifying and targeting subtle epileptogenic lesions, which are difficult to visualize.
