Figure 1: Axial T2WI of right cerebellar hypoplasia in craniocaudal sequence. A: There is marked hypoplasia of the right cerebellar hemisphere and replacement by CSF. The left cerebellar hemisphere is normal in bulk and signal intensity. B: At the level of internal auditory canals, the residual right cerebellum can be seen anteriorly. The normal bulk of vermis can also be seen. C: At the level of medulla, only a thin strip of residual right cerebellum is seen anteriorly. In all the images, the residual right cerebellum shows normal grey white differentiation and foliation. The left cerebellar hemisphere shows normal volume and morphology.
