A 21-years-old male patient with a known diagnosis of NF2 came for follow-up. Bilateral CPA space-occupying lesions are seen. They are hypointense on T1WI (a), hyperintense, extending into and widening the IACs on T2WI (b), showing heterogenous post-contrast enhancement on T1WI+C (c, d), showing signal voids of micro-bleeds on SWI (e, f). The right mass shows hyperintense signal in diffusion with ADC value =1.2 × 10−3 mm2. The left is hypointense on DWI with ADC value of 1.5 × 10−3 mm2 (g). They showed myo-inositol peak on MRS. The findings were matching with the final diagnosis of NF2 with bilateral CPA schwannomas
