The MRI sequences demonstrate a solid extra-axial mass at the left cerebellopontine angle measuring (28 x 24 x 22 mm) with mild enlargement of the ipsilateral porus acusticus. It displays a low signal intensity on T1WI, heterogeneous high signal intensity on T2WI/FLAIR with heterogeneous enhancement and central necrosis on postcontrast sequences.
A mass effect is noted on the brainstem, left middle cerebellar peduncle, a cisternal portion of the trigeminal nerve as well as the cerebellar hemisphere and 4th ventricle which is laminated and displaced to the right
Moderate dilatation of the 3rd and lateral ventricles, indicating obstructive hydrocephalus.
