Dizziness for 9 years. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are scattered foci of high T2 signal in the cerebral white matter and patchy T2 hyperintensity in the pons. The cerebellum appears unremarkable. The inner ear structures and internal auditory canal appear grossly unremarkable. There is no abnormal intracranial 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 are grossly unremarkable. There is extensive mucosal thickening in the right maxillary sinus, where there are also secretions. There is also diffuse mucosal thickening in the ethmoid and left maxillary sinuses.
1. No evidence of intracranial hemorrhage, mass, or acute infarct. 2. Scattered foci of high T2 signal in the cerebral white matter and patchy T2 hyperintensity in the pons are nonspecific, but may represent chronic small vessel ischemic disease. 3. The inner ear structures and internal auditory canal appear grossly unremarkable. 4. Findings suggestive of sinusitis.
