Headaches and history of mesothelioma. There appears to be a punctate focus of enhancement at the grey-white matter junction of the anterior left middle frontal gyrus. There is no evidence of intracranial hemorrhage or acute infarct. There is minimal scattered nonspecific cerebral white matter T2 hyperintensity. 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 orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There is a small amount of fluid within the bilateral mastoid air cells.
A punctate focus of enhancement at the grey-white matter junction of the anterior left middle frontal gyrus may represent a metastases, focally prominent vasculature, or artifact. Close interval follow up may be useful for further elucidation.
