A Case of a Hypopharyngeal Schwannoma.

Hypopharyngeal neurinomas are rare. A 74 year-old male with a hypopharyngeal neurinoma is presented in this report. The patient had no symptomatic complaints, and the tumors were found incidentally. Laryngoscopy was then performed, and a neurinoma was found which had a smooth submucosal surface, was round and was located on the left posterior hypopharyngeal wall. A CT scan showed the mass on the left side of the hypopharynx, with an irregularly-enhanced isodensity portion. MRI imaging was very useful in the preoperative diagnosis, providing much information concerning the extension of the tumor, which could not be obtained by CT.
