Patient Data

Age: 35 years
Gender: Female

A well defined extra-axial mass at the right CPA, showing hypointense T1 and heterogenous T2/FLAIR signal, with internal punctate foci of calcification. Avid enhancement post-Gd administration is seen except for the cystic center.

The mass causes displacement of the adjacent brainstem with obliteration of the contralateral ambient cistern. No extension into the right IAM and the intracanalicular nerves are separable.

Case Discussion

These findings are most consistent with a CPA meningioma. However, no tissue biopsy was obtained.

The main differential diagnosis is a vestibular schwannoma, although less likely.
