7-year-old male with cerebral cavernous malformation, six-month follow-up. There has been continued slight interval increase in size of a posterior right cerebellar hemisphere cavernous malformation, specifically of the more posteriorly located multi locular component which measures 14 x 14 mm in transverse dimension (previously 11 x 12 mm). Additionally, a few of the cystic interstices account for the enlargement, with a heme/fluid level is now evident within the largest. There remains no perilesional edema or significant associated mass effect.There is no appreciable interval change in the numerous other supratentorial and infratentorial cavernous malformations. There is no evidence of acute 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. Mastoid air cells are clear.
