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].
