Meningioma surveillance. There is no significant change in the enhancing right olfactory groove mass, which measures up to approximately 28 mm. There is mass effect upon the overlying inferior right frontal lobe, but no evidence of vasogenic edema. There are a few unchanged nonspecific scattered foci of T2 hyperintensity in the cerebral white matter, as well as small linear area of encephalomalacia in the right thalamus. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There are bilateral lens implants.
1. No significant change in the right olfactory groove meningioma.2. Chronic lacunar infarct in the right thalamus.
