Brain lesion and cyst, abnormal MRI in the past, 3 month post surgical follow up. There has been interval evolution of postoperative findings related to left frontal convexity cyst fenestration, with a small amount of high T1 and low T2 signal extra-axial blood products along the anteromedial left frontal convexity and collapse of the cyst cavity. There is minimal residual T2 hyperintensity in the underwing brain parenchyma and no significant mass effect upon the underlying brain parenchyma. There is no evidence of acute territorial cerebral infarct. 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.
