The MRI sequences demonstrate:
enhancing masses along the acousticofacial bundle bilaterally
enhancing masses spreading along the trigeminal nerves and their divisions with a convex shape and enhancement of the cavernous sinuses, as well as effacement of the pterygopalatine fossa mainly on the left (maxillary division or V2)
marked enhancement along the cranial nerves (IX, X, XI) in the jugular foramen
enhancement along the other cranial nerves, such as the occulomotor (III; axial, coronal) and abducens (VI) nerves.
extensive thickening with enhancement of the basal subarachnoid cisterns
moderate dilatation of the third and lateral ventricles with periventricular transependymal edema suggestive of obstructive hydrocephalus
moderate cerebral volume loss with small vessel ischemic change
