50-year-old woman with history of visual symptoms and abnormal finding on PET CT. No restricted diffusion to suggest acute ischemia. There are no abnormalities on susceptibility weighted images to suggest intracranial hemorrhage. There is a small area of encephalomalacia in the posterior left lingual gyrus (series 701, image 15) with gyriform increased T2 signal and volume loss extending to the left parahippocampal gyrus (series 401, image 15). The brain parenchyma is otherwise unremarkable for age. There is no intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. No abnormal parenchymal or meningeal enhancement is identified. The major flow voids are noted.The sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
1.Chronic-appearing infarct in the left PCA territory corresponding to abnormality seen on PET/CT.2.MRI otherwise within normal limits for age without evidence of intracranial hemorrhage, mass, or acute infarct.
