Dumbbell-shaped Meningioma of Meckel's Cave Mimicking Trigeminal Schwannoma: A Case Report.

INTRODUCTION AND IMPORTANCE:Several meningioma cases arising through Meckel's cave (MC) at the middle and posterior fossa have been reported. However, few relevant meningiomas have been observed with a dumbbell shape.PRESENTATION OF CASE:We report a rare case of a 36-year-old woman with a meningioma of MC with a typical dumbbell-shaped, schwannoma-like presentation on magnetic resonance imaging (MRI), resulting in a misleading differential diagnosis.CLINICAL DISCUSSION:In this case report, we discuss the characteristics of meningioma of MC observed on MRI and our surgical approach to this condition.CONCLUSION:This tumor was able to mimic a trigeminal schwannoma both clinically and radiographically. This case report has been reported in line with the SCARE 2020 criteria [1].
