Glossopharyngeal neuralgia is a rare condition with a frequency about 1% of that of trigeminal neuralgia. Vascular compression is a common and treatable cause of glossopharyngeal neuralgia. Microvascular decompression of the glossopharyngeal nerve is an effective treatment option for patients in whom the disease is caused by compression of the nerve by a blood vessel. Pre-operative detection of the pathology on imaging has become possible with high strength MRI imaging. We describe the case of a 54-year-old man with left glossopharyngeal neuralgia. Constructive interference in steady-state (CISS) and flow sensitive Gradient Echo MRI sequences clearly demonstrated the compression of the IX nerve by the left posterior inferior cerebellar artery (PICA). The patient was operated upon and a Teflon graft was put in between the nerve and the vessel. The intra-operative photographs and post-operative images are also presented here. After surgery, the patient improved symptomatically with no recurrence of the symptoms in the follow-up period of about eight months.
