Postoperative changes include a resection cavity with a mild amount of adjacent parenchymal hemosiderin staining. Redemonstrated is the associated prominent developmental venous anomaly.The remainder of the brain demonstrates no additional 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.
