Heterogeneous signal in the right cerebellopontine angle is demonstrated, which is high on T2, incompletely attenuates on FLAIR and of low T1 signal with no enhancement. It causes moderate local mass effect. There is high DWI signal and intermediate ADC values.
Case Discussion
Typical appearances of an epidermoid cyst.
The patient went on to have a craniotomy which confirmed the diagnosis histologically.
