Hearing loss. 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 no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. However, there is a cystic pineal gland that measures up to 12 mm with linear peripheral enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. No evidence of inner ear abnormalities or cochlear nerve deficiency.2. Cystic pineal gland that measures up to 12 mm likely represents benign cystic change. However, a one year follow up brain MRI may be considered.
