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