 Redemonstrated is a mass within the right frontal lobe that measures approximately 3.0 x 4.1 x 2.4 cm (CC x AP x T) with heterogenous signal in the FLAIR, mostly low to intermediate signal, and increased T2 signal. It contains peripheral nodular enhancement although center of the lesion is nonenhancing. Susceptibility images demonstrates low signal which is consistent with hemorrhage. There is associated high T2 signal in the adjacent brain parenchyma which corresponds to vasogenic edema and involves the right frontal, right parietal, and the right temporal lobes. Portions of the mass also involves the left frontal lobe with 7 mm midline shift to the left and vasogenic edema surrounding the portion of the mass in the left frontal lobe. Mass effect is seen partially obstructing the anterior horn of both lateral ventricles and deforms the genu of the corpus callosum. Basal cisterns are patent. No evidence of uncal herniation.There are mild chronic periventricular white matter and pons small vessel ischemic changes. Diffusion images demonstrates no restricted diffusion. No evidence of extra-axial fluid. Paranasal sinuses and the mastoid air cells are well pneumatized.
Mass in the right frontal lobe with extensive vasogenic edema surrounding the mass extending to the right parietal and right temporal lobes. The mass extends also involves the left frontal lobe with midline shift to the left, deformation of the corpus callosum genu, and compression of the anterior horns of the lateral ventricles.
