Legend T2 and FLAIR images demonstrate a large hypointense left fronto-parietal lobe mass with surrounding mild edema, but no significant midline shift. An additional, smaller cortical lesion is seen in the right frontal lobe.

Legend FLAIR and T1WI confirm some late subacute hemorrhage in both lesions.

Legend Gradient echo images demonstrate blooming (susceptibility) in the left parasagittal and right frontal lesions, as well as additional foci of parenchymal and leptomeningeal susceptibility artifact. There is restricted diffusion in the right frontal lobe lesion. No restricted diffusion is seen in the left parasagittal lesion, but susceptibility artifacts are quite prominent in that area.
