63 years, Male, with history of malignant melanoma. There is a 7 mm enhancing lesion with a mild amount of surrounding edema in the high right posterior frontal lobe/paracentral lobule (series 1001 image 29). No additional enhancing lesions are seen intracranially.No restricted diffusion is present to suggest acute ischemia. No intracranial hemorrhage. The ventricles and other CSF spaces are mildly prominent, compatible with mild parenchymal volume loss.A perivascular space or small chronic lacunar infarct is noted in the left globus pallidus. Several foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with chronic small vessel ischemic changes. No abnormal dural or leptomeningeal enhancement. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
