Dysembryoplastic neuroepithelial tumours (DNET) are a common cause of tumour-associated epilepsy, and are usually located in the temporal lobes. We present a case of multifocal DNETs in both infra- and supra-tentorial locations, in a 23-year-old man with a coincident Type I Chiari malformation, presenting with medically refractory focal seizures. The extensive anatomical distribution of the lesions suggests a genetic component in their tumourigenesis.
