Dysplastic gangliocytoma and intractable partial seizures in childhood

We describe the clinical, radiologic, and EEG features of 3 children who had dysplastic gangliocytomas of the cerebral hemispheres and drug resistant partial seizures that began in infancy. Following cortical resection, 2 are seizure-free and the third almost seizure-free. The dysplastic gangliocytoma may be an important and surgically remediable cause of very early malignant partial seizures.
