Features consistent with an intracranial, insinuating, left cerebellopontine angle, extra-axial epidermoid cyst with typical signal intensities on pre-contrast imaging, and heterogeneous signal on T2 Flair imaging.
There is a heterogeneous signal on diffusion imaging due to a combination of true diffusion and shine-through artifact as evidenced by the associated ADC mapping.
There is a mass effect on the left pons and medulla with a displaced vertebral artery towards the right.
There is no abnormal enhancement.
MRI brain is otherwise normal.
