Sensorineural hearing loss and tinnitus of the right ear. The bilateral cranial nerve 7 and 8 complexes are grossly intact. There is no evidence of mass lesions, although the postcontrast sequences are degraded by patient motion. 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 encephalomalacia in the right lateral temporal lobe. There is also scattered patchy cerebral and pontine white matter T2 hyperintensity. There is a right maxillary sinus retention cyst.
1. No evidence of retrocochlear or inner ear lesions, although the postcontrast sequences are degraded by patient motion.2. RIght lateral temporal lobe chronic infarction and scattered probable chronic small vessel ischemic white matter disease.
