 There is thick pial enhancement as well as possibly a dura/arachnoid component within the right frontal lobe centered within the precentral sulcus. There is some probable subtle contrast leakage within the adjacent brain parenchyma as well as surrounding T2 hyperintensity compatible with edema that does involve the right precentral gyrus. There is also associated parenchymal susceptibility effect compatible with blood products. There is no evidence of acute 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. The skull, paranasal sinuses, and scalp soft tissues are unremarkable.
Focal meningeal thickening and enhancement centered within the right precentral gyrus with associated adjacent parenchymal involvement. These findings are most compatible with metastasis but infection could have a similar appearance.
