Figure 2 Magnetic resonance imaging at second recurrence. A-C: Brain magnetic resonance imaging (MRI) T1-weighted postcontrast image (A) axial, (B) transverse, (C) sagittal, which shows irregular soft tissue with heterogeneous hyperintense signals and subtle contrast enhancement in the right cerebellopontine angle cistern and annular cistern (arrow); D and E: Axial MRI T2-weighted imageshows isointensity, while axial MRI T1-weighted image (E) shows a hypointense mass with an unclear boundary with the right tentorium and brain stem compression (July 10, 2021, before the 3^rd operation).
