Left cerebellopontine angle, lobulated outline mass lesion shows the following characters; High signal on T2 and low signal on T1 (near isointense to CSF) it does not fully attenuate on FLAIR, instead of having a dirty, heterogeneous appearance. There is no contrast-enhancing component and it does not extend into the internal acoustic meatus (cranial nerves going through the lesion). On diffusion-weighted imaging (DWI) and (ADC) which demonstrates restricted diffusion. Exerting mild presser mass effect on the adjacent brain stem. The finding demonstrates typical appearances of left cerebellopontine angle epidermoid cyst.
Otherwise normal appearance of the cerebral hemispheres, corpus callosum, posterior fossa, with preserved gray/white matter differentiation.
