Atypical meningioma status post resection on 7/14/2015. There are postsurgical findings related to left frontal craniotomy for resection of a left frontal convexity meningioma. There is a small amount of scattered blood products and trace confluent T2 hyperintensity surrounding the resection cavity. There is mild dural thickening and enhancement overlying the resection cavity, as well as a few punctate foci of enhancement along the margins of the surgical cavity. There is minimal ex vacuo dilatation of the frontal horn of the left lateral ventricle. Otherwise, the ventricles and basal cisterns are normal in size and configuration. There is unchanged mild predominantly periventricular nonspecific cerebral white matter T2 hyperintensity. There is no midline shift or mass effect. There is no evidence of acute infarction. There is scattered fluid signal in the mastoid air cells, right greater than left. There are bilateral lens implants.
