Tolosa-Hunt syndrome is a rare cause of painful ophthalmoplegia due to idiopathic chronic granulomatous inflammation in the cavernous sinus. Usually clinical manifestations are well controlled by corticosteroid therapy, but steroid dependency or resistance is common. We report a case of marked improvement of Tolosa-Hunt syndrome without symptom relapse after Gamma Knife radiosurgery in a patient with steroid intolerance.
