The glossopharyngeal neurinoma. Case reports and literature review.

Glossopharyngeal neurinomas are rare entities. Only 16 cases have been described so far in the literature. Our experience with 2 cases demonstrates the non-specific and discrete clinical presentation of the ninth nerve neurinoma, but illustrates also some typical radiological aspects, enabling a more precise preoperative diagnosis. Two cases are presented and a survey of the literature is given.
