Rght cerebello-pontine angle mass, which is iso-intense to grey matter T1 signal, high signal on FLAIR and T2WI, and enhances vividly on postcontrast images. There is mass effect on the adjacent midbrain and pons. The basilar artery is displaced to the left but appears separate free from the mass. The mass appears separate from the seventh and eighth cranial nerves on these thick slices. Anteriorly the mass extends towards the right Meckel's cave, cavernous sinus and internal carotid artery. There is also associated dural thickening of the adjacent tentorium cerebelli.
There is a separate mass, which arises from the left anterior clinoid process. This has similar characteristics to the right CPA mass. This is in close association with the terminal left internal carotid artery bifurcation.
