Dizziness, unilateral right tinnitus and sensorineural hearing loss. There is a vascular structure that courses adjacent to the proximal cisternal segments of the right cranial nerve 7 and 8 complex. The bilateral cranial nerve 7 and 8 complexes are otherwise intact. There is no evidence of mass lesions. The inner ear structures, including the cochlea, vestibule, endolymphatic duct, and semicircular canals, appear unremarkable. The bilateral mastoid air cells and middle ears also appear unremarkable. There are scattered foci of T2 hyperintensity in the imaged portions of the cerebral white matter. There are bilateral lens implants.
1. A vascular structure that courses adjacent to the proximal cisternal segments of the right cranial nerve 7 and 8 complex is of indeterminate significance. 2. Scattered foci of T2 hyperintensity in the imaged portions of the cerebral white matter are nonspecific, but may represent chronic small vessel ischemic disease.
