Cerebellopontine angle lipoma

Case contributed by Frank Gaillard
Diagnosis almost certain
mri

T1 weighted image demonstrates a small hyperintense nodule of tissue surrounding the facial / vestibulocochlear nerve in the cerebellopontine angle. On post contrast fat saturated imaging, no enhancement is identified and the entire mass demonstrates attenuation in keeping with it being composed of fat. Features are thus those of an intracranial lipoma.
