Résumé
The symptoms of dural arteriovenous fistula (dAVF) vary according to the location of the fistula and the pattern of venous drainage. Here, we report the case of a patient with a dAVF-induced glossopharyngeal neuralgia. We report a case of a patient with right glossopharyngeal neuralgia caused by a posterior condylar canal (PCC) dAVF. The glossopharyngeal neuralgia was accompanied by persistent tinnitus and repetitive right side otalgia, as well as ipsilateral shoulder and throat pain, lasting for about 30 s. However, there were no specific findings on otoscopic examination. Cranial magnetic resonance imaging was performed to determine the cause of the symptoms, and a right PCC dAVF was observed. The dAVF was successfully obliterated using transvenous coil embolization. After embolization, the patient's symptoms were completely resolved. Although glossopharyngeal neuralgia caused by dAVF is rare, it can present due to intracranial lesions located adjacent to the glossopharyngeal nerve or vagus nerve. Brain MRI is therefore required to identify secondary causes in all patients with glossopharyngeal neuralgia.

BACKGROUND
The symptoms of dural arteriovenous fistula (dAVF) vary according to the location of the fistula and the pattern of venous drainage. Here, we report the case of a patient with a dAVF-induced glossopharyngeal neuralgia.
CASE DESCRIPTION
We report a case of a patient with right glossopharyngeal neuralgia caused by a posterior condylar canal (PCC) dAVF. The glossopharyngeal neuralgia was accompanied by persistent tinnitus and repetitive right side otalgia, as well as ipsilateral shoulder and throat pain, lasting for about 30 s. However, there were no specific findings on otoscopic examination. Cranial magnetic resonance imaging was performed to determine the cause of the symptoms, and a right PCC dAVF was observed. The dAVF was successfully obliterated using transvenous coil embolization. After embolization, the patient's symptoms were completely resolved.
CONCLUSION
Although glossopharyngeal neuralgia caused by dAVF is rare, it can present due to intracranial lesions located adjacent to the glossopharyngeal nerve or vagus nerve. Brain MRI is therefore required to identify secondary causes in all patients with glossopharyngeal neuralgia.
