Atypical meningioma status post surgery: surveillance. There are postoperative findings related to right transfrontal resection of a planum sphenoidale meningioma. There is a plaque-like areas of heterogeneous enhancement along the posterior right planum sphenoidale, which measures approximately 25 mm in diameter and 5 mm in thickness. There is a persistent focus of enhancement along the right frontal lobe resection cavity posteromedial margin. A more linear focus of enhancement laterally along the resection cavity margin is likely vascular in nature. There is unchanged diffuse confluent T2 hyperintensity in the right frontal lobe surrounding the resection cavity, as well as to a smaller extent in the left anterior left frontal lobe periventricular white matter. There is no evidence of 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 orbits are grossly unremarkable.
Postoperative findings related to right transfrontal resection of a planum sphenoidale meningioma without significant change in what may represent a small amount of residual tumor along the right planum sphenoidale associated with hyperostosis and along the right frontal lobe resection cavity posteromedial margin.
