 Redemonstrated are multiple foci of susceptibility abnormality within the supratentorial brain, consistent with the diagnosis of cerebral cavernous malformations. None demonstrate perilesional edema. There are no associated developmental venous anomalies. Previously identified lesions which had enlarged on the comparison exam demonstrates some change of internal signal characteristics, however none currently have significantly enlarged.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. The pituitary gland is normal in size. There is no evidence for acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The mastoid air cells are clear. There is no abnormal enhancement within the brain.
