Patient Data

Age: 65 years
Gender: Female

 A well-circumscribed extra-axial soft tissue mass at the left cerebellopontine angle with broad-based dural attachment, extending into the ipsilateral internal auditory canal, enlarging the porus acusticus. It demonstrates an intermediate signal intensity on T1WI, mild high signal intensity on T2WI/FLAIR with intense and homogeneous enhancement on postcontrast sequences with "dural tail sign". There is a mass effect on both VII and VIII cranial nerves which are displaced inferiorly as well as on the origin of the trigeminal nerve and middle cerebellar peduncle.

Case Discussion

MRI features characteristic of a cerebellopontine angle meningioma. The main differential diagnosis is vestibular schwannoma.
