Glossopharyngeal neuralgia associated with vascular compression and choroid plexus papilloma.

We report two cases of presumed idiopathic glossopharyngeal neuralgia that were discovered intraoperatively to be associated with compression by choroid plexus papillomas, and by a variable degree of vascular compression at the root entry zones of cranial nerves IX and X. The combination of the two entities in glossopharyngeal neuralgia has not previously been reported.
