Confusion, evaluate for progression or recurrence of cerebellar cavernoma. There are post-surgical changes of a prior suboccipital craniotomy with underlying resection of a left anteromedial cerebellar cavernous malformation. There is a mild amount of residual hemosiderin staining at the resection cavity. Redemonstrated is a prominent adjacent developmental venous anomaly. The remainder of the brain demonstrates no new cavernous malformations, or other mass or mass effect. There is mild hypoplasia involving the inferior cerebellar vermis. Brain parenchyma is otherwise unremarkable for age. There is no restricted diffusion to suggest acute ischemia. The ventricles are within normal limits in size and configuration. No abnormal parenchymal or meningeal enhancement. Sella and orbits are within normal limits. The paranasal sinuses and mastoid air cells are clear.
Post-surgical findings of suboccipital craniotomy for resection of a left anteromedial cerebellar cavernous malformation are again seen. Small resection cavity demonstrates slight evolution but is otherwise unchanged including mild amount of adjacent parenchymal hemosiderin staining. No new cavernous malformations.
