Figure 5. Case 2. MRI with (a) axial T2 weighted imaging and (b) fluid attenuation inversion recovery (FLAIR) images and (c) coronal T1 weighted image after infusion of gadolinium revealing a swollen right cerebellar hemisphere, with high signal intensity in long repetition time sequences and hypointensity in T1 weighted imaging affecting both the cortex and the white matter. The superior vermis is also affected. There is mass effect over the fourth ventricle.
