DYSEMBRYOPLASTIC NEUROEPITHELIAL TUMORS IN 2 CHILDREN WITH NEUROFIBROMATOSIS TYPE-1

Dysembryoplastic neuroepithelial tumors (DNT) occur mainly in children and are always clinically associated with intractable complex partial seizures. In the first report, which included 39 cases, the patients had no neurological deficit and no stigmata of phacomatosis. In contra st, we observed a DNT in 2 children with a neurofibromatosis type 1. T he first patient developed intractable complex partial seizures at age 9 years and was operated at the age of 13 years. Neuroimaging study s howed multifocal involvement with three separated lesions in the front al, parietal and temporal lobes. The second patient was a 16-year-old boy with 5-year history of severe and refractory epilepsy. Magnetic re sonance imaging identified a right temporal lesion and the patient und erwent a right temporal lobectomy. This unusual association of two cas es of DNT with neurofibromatosis type 1 raises the question of whether this association is specific or fortuitous.
