One year follow up for cavernous malformations. There are innumerable cavernous malformations throughout the supratentorial and infratentorial brain. Subcentimeter lesions in the left middle cerebellar peduncle and in the right superior cerebellar hemisphere appear to be slightly larger, but there is no evidence of acute hemorrhage or associated edema. The other lesions appear to be essentially unchanged. There is no convincing evidence of associated developmental venous anomalies. The ventricles and basal cisterns are unchanged in size and configuration, without midline shift. There is no evidence of acute infarct. The paranasal sinuses, mastoid air cells, and orbits are unremarkable.
Innumerable supratentorial and infratentorial cavernous malformations, with slight interval increase in size of subcentimeter lesions in the posterior fossa, but no evidence of acute hemorrhage or associated edema.
