Atypical meningioma surveillance. There are postoperative findings related to right transfrontal resection of a planum sphenoidale meningioma. There is an unchanged plaque-like area of heterogeneous enhancement along the posterior right planum sphenoidale, which measures approximately up to 5 mm in thickness. There is a persistent punctate focus of enhancement along the right frontal lobe resection cavity posteromedial margin. There is unchanged diffuse confluent T2 hyperintensity in the right frontal lobe surrounding the resection cavity, as well as 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 the small amount of residual tumor along the right planum sphenoidale associated with hyperostosis. Persistent nonspecific punctate focus of enhancement along the right frontal lobe resection cavity posteromedial margin.
