A Rare Case of Glossopharyngeal Neuralgia due to Neurovascular Conflict.

In the context of painful cranial neuropathies, a very rare cause is represented by the irritation of the glossopharyngeal nerve due to various aetiologic factors. Here, we present a case of neuralgia of the ninth right cranial nerve due to a compression of its nerve root upon the kinking of the homolateral vertebral artery, resulting in a disabling clinical overview for the patient. Our objective was to focus the reader's attention on the clinical manifestation, which alone could lead to an immediate diagnosis.
