(A) Postgadolinium T1-weighted axial image shows the right skull base chondrosarcoma projecting into the CPA cistern. The right IAC appears normal with a small vessel seen as the enhancing linear structure near the canal. (B) Oblique reformat of CISS data shows CNs VII and VIII in the right CPA and IAC. AICA, anterior inferior cerebellar artery. (C) Oblique reformat of CISS data shows a vessel anterior to the right IAC. (D) Surface-rendered model from the navigational model shows the tumor near CNs VII and VIII. The vessel is also identified near the IAC. CPA, cerebellopontine angle; IAC, internal auditory canal; CISS, constructive interference in the steady state; CNs, cranial nerves.
