 Redemonstrated are numerous foci of magnetic susceptibility artifact of the brain consistent with the history of multiple cavernous malformations. The lesions primarily involve the cerebral hemispheres but are also noted within the cerebellum and brainstem.There is at least one definite new lesion within the medial left parietal lobe (best seen series 901 image 20) containing T1 hyperintensity however without perilesional edema. There has also been significant increase in size of a right posterolateral pontine lesion, now measuring up to 8 mm in maximal dimension (best seen series 901 image 8) containing T1 hyperintensity however without perilesional edema.Aside from the cavernomas there are no additional parenchymal lesions. No abnormal postcontrast enhancement. The ventricles and sulci are symmetric and normal in size. No significant mass-effect, midline shift, or basal cistern effacement. The midline structures are unremarkable. There is no evidence for acute infarction. There are no extraaxial fluid collections. Flow voids are present within the major vessels. The paranasal sinuses and mastoid air cells are clear.
