Cerebellopontine angle lipoma

Case contributed by Dr Prashant Gupta

Presentation

MRI requested for non specific headache

Patient Data

Age: 60
Gender: Female
MRI

A well defined right cerebellopontine angle mass is seen that is hyperintense on T1 and T2, it is completely suppressed on the T2 fat/sat images 

CT

The NCCT confirms fatty nature of the lesion, the VIII nerve is seen to course through the mass with no apparent mass effect. few peripheral calcific foci are seen- also a known feature of lipoma

Case Discussion

Cerebellopontine angle lipoma comprise 10% of all intracranial lipoma. the differential would include a dermoid- but these are midline leison and very rare at CP angle. However secondary CP angle involvement is described in suprasellar dermoids.
