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.
