Résumé
Ganglioneuroma is a rare tumor. Such tumor arising from cranial nerve is further rare. So far our knowledge, in the literature there is no report of ganglioneuroma involving glossopharyngeal nerve. Here, we report a case of very small glossopharyngeal nerve ganglioneuroma and the patient also had longstanding glossopharyngeal neuralgia (GPN). Case Report: A 40-year-old male diagnosed case of left GPN for last 7 years presented with gradual unresponsiveness of drug for last 5 years. Due to severity of pain sometime, he wished to do suicide. Magnetic resonance imaging (MRI) of head revealed only suspected loop of vessel in root entry zones of 9th and 10 cranial nerves on left side. The patient underwent explorative posterior fossa craniotomy. Careful dissection of arachnoid over 9th cranial nerve near jugular foramen (JF) revealed thick and red color nerve with nodularity (tumor like). Dissection of arachnoid at nerve root entry zones of 9th and 10th nerves also revealed an aberrant loop of posterior inferior cerebellar artery (PICA). The 9th nerve was transected and suspected "tumorous portion" of nerve was sent for histopathological examination. The PICA loop was dissected away from root entry zones by placing muscle and surgical between 10th nerve roots and PICA loop. He made an uneventful recovery. Histopathological examination revealed ganglioneuroma. Immunohistochemistry confirmed ganglioneuroma. Six months after the operation, he was free of symptoms. In this case, probably previously existing GPN was worsen by the growth of ganglioneuroma and surgical treatment brought gratifying result.
