FIG 4. A 39-year-old woman (group 3) with cerebellar lymphoma.
A, Axial T2-weighted image shows an isointense left cerebellar mass surrounded by hyperintense area of vasogenic edema.
B, Axial ADC map corresponding to A reveals relatively decreased diffusion within the mass with surrounding increased diffusion of the vasogenic edema. Relatively low diffusion rate is indicative of high cellularity of the mass.
C, Postcontrast fat-suppressed axial T1-weighted corresponding to A and B images demonstrates attenuated homogenous enhancement of the mass.
