[A post-styloid mass revealing a parapharyngeal schwannoma].

INTRODUCTION

The schwannoma of the glossopharyngeal nerve is a rare etiology among the tumor masses developed in the parapharyngeal space.

CASE REPORT: We report the case of a 33 years old woman in whom a large schwannoma of the left glossopharyngeal nerve was discovered incidentally on a brain MRI. Respiratory evolutionary prognosis imposed trans-oral surgical treatment.

DISCUSSION: We discuss the diagnostic and therapeutic strategy for the benign tumors of the parapharyngeal space.

CONCLUSION

The schwannoma of the glossopharyngeal nerve is a benign rare lesion. The difficulty lies on the surgical strategy and the choice of the approach. The functional suites are marked by difficulty swallowing and require intensive speech therapy.
