Multiple cerebral cavernous malformations. There is slight interval increase in size of a posterior right cerebellar hemisphere cavernous malformation with interval appearance of central T1 hyperintense components, with an adjacent small developmental venous anomaly. There is no appreciable interval change in the numerous other supratentorial and infratentorial cavernous malformations. There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Slight interval increase in size of a posterior right cerebellar hemisphere cavernous malformation likely attributable to subacute hemorrhage. Otherwise, no appreciable interval change in the numerous supratentorial and infratentorial cavernous malformations.
