Presentation
Trauma. Bleed?
Patient Data
4.1cm heavily calcified right cerebellopontine angle mass. Suggestion of possible intracannilicular extension but no expansion.
Mild-moderate mass effect on the right hemipons and middle cerebellar peduncle.
Partial effacement of the 4th ventricle. No hydrocephalus.
Normal supratentorial brain.
Case Discussion
This case illustrates a incidental cerebellopontine angle (CPA) mass.
Meningiomas are common at this site and often calcify. However, the main differential at the CPA is a vestibular schwannoma. These rarely calcify although the 'ice cream' type morphology and suggestion of intracannilicular extension is more in keeping with a schwannoma.
MRI of the IAM's would assist in a definitive diagnosis if further investigation was felt merit/necessary.
