[A case of intracranial osteochondroma originating with psychomotor epilepsy].

A 28-year-old woman was admitted to our clinic due to psychomotor epilepsy. Craniogram, CT scan demonstrated a calcified lesion in the frontal, parasagittal region. MR proton images showed a mixed hyper-and hypodense lesion. The tumor originated from the frontal bone and was totally removed using airdrill safely. Histological findings revealed osteochondroma originating in the frontal bone is rare, and diagnostic procedures and surgical management of this tumor are discussed.
