Fig 2. A, Axial T2-weighted TSE (4000/99 [TR/TE]) image shows a large vermian mass with a complete hemorrhagic ring and surrounding edema. A small right cerebellar hyperintense lesion is also seen.
B, Postcontrast sagittal T1-weighted SE (550/15) image demonstrates ring enhancement of the vermian lesion.
C and D, DWI (2800/78; b of 0, 500, 1000 seconds/mm2 in 3 axes; 256 x 256 matrix; 230 mm FOV; C) and ADC (D) images show decreased diffusion at the center of the vermian lesion as well as at the right cerebellar lesion.
