Ganglioneuromas are rare tumors arising from retroperitoneal and posterior mediastinal sympathetic nerves. Intracranial trigeminal nerve ganglioneuromas are even more rare, with only seven cases reported to date. We present a case of a 65-year-old male with a right-sided throbbing headache type and blindness in his right eye. Magnetic resonance imaging revealed an ill-defined mass lesion in the middle-cranial fossa, with a few areas having a reduced apparent diffusion coefficient and multiple microhemorrhages. Piecemeal debulking of the tumor was achieved by performing a right-middle craniotomy via the pterionic and sub-temporal approach. The detected histological features matched those of a ganglioneuroma (maturing type) of the trigeminal nerve.
