MRI of Glossopharyngeal Neuralgia Caused by Neurovascular ...
MRI may be beneficial in patients with glossopharyngeal neuralgia and an offending compressing artery. If the offending vessel was the posterior inferior cerebellar artery (PICA), a loop formation at the supraolivary fossette was always seen, whereas if it was the anterior inferior cerebellar artery (AICA), glossopharyngeal neuralgia was difficult to diagnose before surgery.

Background and purpose: Glossopharyngeal neuralgia causes extreme paroxysmal pain in the posterior pharynx, tonsillar region, base of tongue, or deep ear, that is, the distribution of the glossopharyngeal nerve. Some cases of glossopharyngeal neuralgia are associated with neurovascular conflict, usually by the posterior inferior cerebellar artery. Such symptomatic compression occurs only in proximal, centrally myelinated portions of the glossopharyngeal nerve …

Imaging of the glossopharyngeal, vagus, and accessory nerves
The origination and course of the glossopharyngeal, vagus and accessory cranial nerves explains their function and localizes pathology. Abnormalities of these lower cranial nerves may be intrinsic or extrinsic and is due to a multiplicity of disease processes. The clinical presentation of the involved cranial nerve helps to guide imaging evaluation.
