title: Arachnoid cysts with intracystic and subdural haematoma.
abstract: Two cases of arachnoid cysts with acute intracystic and subdural haematomas are described. CT examination was performed in both cases, and showed a hyperdense expansion with thinning of the inner table of the skull. The different ways in which subdural haematomas associated with arachnoid cysts may be seen on CT are discussed.
