Figure 2 T1 axial (A) and FLAIR coronal (B) images of a 6-year-old boy showing a large well-defined solid mass lesion (arrows) in the midline arising from the vermis and appearing hypointense on T1WI, hyperintense on FLAIR with few necrotic areas within. Axial DWI (C) shows diffusion restriction with marked postcontrast enhancement (D). Drop metastases is also seen on postcontrast image of the spine (E) − imaging features are suggestive of group 3 subtype of medulloblastoma.
