Right CN VII schwannoma in the cerebellopontine angle (CPA) in a patient with neurofibromatosis type II. Axial CISS sequence (a) demonstrates a small lesion along CNVII (black arrow), which courses anterior to CNVIII (white arrowhead) in the right CPA cistern. Axial T1 postcontrast fat-saturated images (b)-(c) demonstrate the enhancement of the right facial schwannoma (solid white arrow, (b)). Also note the vestibular schwannoma in the right IAC (dashed white arrow, (c)) and residual enhancement with postsurgical changes in the region of the left IAC.
