A Case of Monostotic Fibrous Dysplasia of the Temporal Bone Asso­ciated with Epileptic Seizure

An 11-year-old male with monostotic fibrous dysplasia of the left temporal bone was reported. At the age of seven years, the patient began having epileptic attacks, and a bony swelling of the left temporal region was noticed by his mother. Roentgenologically, there were almost thorough osseous obstruction and osseous proliferation of the external auditory canal and pars petrosa, respectively. Audiologic examinations indicated gradual functional disturbance based on the affected internal ear. A total of 20 cases with monostotic fibrous dysplasia of the temporal bone reported between 1946 and 1980 was analyzed, and the association of fibrous dysplasia and epilepsy was discussed.
