Predominantly solid lesion with small areas of cystic degeneration / necrosis and possible foci of hemorrhage in posterior fossa in midline. Lesion is expanding the 4 th ventricle, splaying bilateral middle cerebellar peduncles and brainstem anteriorly. No obvious extension of lesion is seen into foramen of Magendie or Luschka. Cerebellar vermis is not well visualized separately. Lesion shows diffusion restriction with mild heterogeneous enhancement on post contrast study.
Case Discussion
