A 14-year-old male patient presented with the chief complaint of tremors in his left arm and leg, and a history of seizures since age 3. The patient had been diagnosed with partial epilepsy, and had been taking anticonvulsant medication for 6 years. He had been having four to five seizures a day in the year prior to presentation at our center. Since the patient's condition had not improved with the drug treatment, he was referred to the Neurosurgery Outpatient Clinic. A neurological examination revealed no pathological findings. Computerized tomography and magnetic resonance imaging showed a 2x1x1cm space-occupying lesion located in the cortical and subcortical regions of the right parietal lobe. The mass did not enhance with contrast injection. Digital subtraction -angiography findings were normal. The patient's electroencephalogram showed epileptic discharges that started in the right hemisphere and then rapidly generalized. The preliminary diagnosis was a low-grade glial tumor, and the patient underwent surgery. The mass was easily reached with the stereotactic laser beam. The tumor was gr ay-white, had minimal blood supply, and its borders were not easily distinguishable from the surrounding normal tissue. The tumor was completely removed. The patient experienced no seizures during 4 years of postoperative fol1ow-up, and his electroencephalogram findings were normal in the fourth year.
