Case #32

CT

• Round, hyperattenuating mass in the left frontal lobe with surrounding vasogenic edema

MRI

• T1 hypointense, T2 isointense mass with a rim of relative T1 signal hyperintensity and T2 signal hypointensity in the left frontal lobe measuring 3.4 x 3.3 x 3.2 cm with finger-like enhancing projections and a satellite enhancing lesion more superiorly in the left frontal lobe
• Homogeneous, diffuse corresponding enhancement and restricted diffusion
• No associated susceptibility artifact
• Surrounding vasogenic edema and corresponding mass effect resulting in local sulcal effacement, crowding of the left lateral ventricle, and left-to-right midline shift measuring 4 mm
• No downward herniation or hydrocephalus
