Glossopharyngeal schwannoma, an uncommon posterior fossa tumor: diagnostical and therapeutical aspects: a case report.

ABSTRACT

Among posterior fossa tumors, schwannomas arising from glossopharyngeal nerve are rare; only about 30 cases of glossopharyngeal neuroma have been described. Though a typical 'jugular foramen syndrome' has been described for tumors of this region, the clinical onset may often closely resemble that of acoustic neuromas thus misleading the diagnosis. Because of its different surgical implications, such a rare condition must be clearly recognised preoperatively. A new case is hereby reported with particular focus on clinical and surgical management.
