GLOSSOPHARYNGEAL SCHWANNOMA, AN UNCOMMON POSTERIOR-FOSSA TUMOR - DIAGNOSTICAL AND THERAPEUTIC ASPECTS - A CASE-REPORT

Among posterior fossa tumors, schwaanomas arising from glossopharyngea l 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 clos ely 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 neu-case is hereby report ed with particular focus on clinical and surgical management. (C) 1991 Elsevier Science B.V.
