Bifocal temporal ganglioglioma

The authors present the case of a 33-year-old patient with a bifocal gangli oglioma located in the right superior temporal gyrus. He had a history of t onic-clonic seizures and developed intermittent nausea and vertigo later on . Magnetic resonance imaging showed two distinct, small lesions in the righ t temporal lobe. Both tumors were removed microsurgically with ultrasound g uidance. Intraoperatively, two distinct tumors were found. Histological dia gnosis of both tumors was of ganglioglioma WHO II. Postoperatively, the pat ient was free of symptoms. Bifocal occurrence or the coincidence of two dis tinct gangliogliomas is a very uncommon finding. So far, it has not yet bee n reported in benign gangliogliomas.
