 Lack of contrast enhancement limits examination.No evidence of a mass, mass effect, or midline shift. Mild prominence of the ventricles and sulci, likely age related volume loss. Mild-to-moderate periventricular and subcortical white matter T2/FLAIR signal abnormality consistent with chronic small vessel ischemic disease. No evidence of acute intracranial hemorrhage or diffusion weighted abnormalities to suggest acute ischemia. The cerebellar tonsils are in normal position. The pituitary gland is normal in size. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear.
Within the limitation of a noncontrast examination, no evidence of intracranial or IAC abnormality to explain the patient's tinnitus.
