There is a well delineated lobulated lesion that is insinuating along the basal cisterns, seen in the right cerebellopontine angle. The lesion is heterogeneous and follows CSF signal intensity on T1W and T2W imaging, partially attenuated on FLAIR and shows restricted diffusion and showing ADC similar to brain parenchyma. Post contrast scan shows no enhancement. Imaging findings are suggestive of epidermoid cyst.
The lesion is compressing the right cerebral peduncle, midbrain, pons, cerebellar hemisphere, vermis and 4th ventricle.
