Male, 69 years old, with sudden right-sided hearing loss. Scattered foci of periventricular and subcortical T2 hyperintensity are seen without edema or mass effect. No restricted diffusion is demonstrated. No pathologic parenchymal or extra-axial enhancement is observed. There are no findings to suggest acute intracranial hemorrhage or any abnormal extra-axial fluid collection. Ventricular size and morphology are within normal limits. High-resolution imaging of the IACs demonstrates a normal appearance of cranial nerves VII and VIII. The IACs are patent and free of mass lesions. The fluid-filled structures of the inner ear are within normal limits.
1.Scattered small parenchymal lesions are seen which most likely reflect chronic microvascular ischemia.2.No evidence of acute ischemia or any other specific finding which would account for the patient's symptoms.
