Epidermoid cyst (small pre-pontine)

Case contributed by A.Prof Frank Gaillard

Patient Data

Age: Adult
Modality: MRI

MRI demonstrates a small region in the pre-pontine cistern with distortion of basilar and vessles which are elevated away from the brain stem. It closely matches CSF on all sequences except DWI which demonstrates increased signal (combination of T2 shine through and restricted diffusion). 

Features are consistent with an epidermoid cyst
