Asymmetrical SNHL, right more than left and right tinnitus. The bilateral cranial nerve 7 and 8 complexes are 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 is partially imaged probable small area of encephalomalacia in the right basal ganglia, which may represent a chronic lacunar infarct.
No evidence of retrocochlear or inner ear lesions.
