 Changes are noted from previous craniotomy involving the skull bilaterally. Encephalomalacia is present involving the anterior right temporal lobe with adjacent gliosis as well as susceptibility abnormality from presumed hemosiderin staining.There are multiple foci of T2 hypointensity with matching susceptibility abnormality throughout the supratentorial and infratentorial brain. More foci of hypointensity are noted with susceptibility technique. The largest of these lesions resides in the left periatrial white matter measuring approximately 11 x 14 mm in transaxial dimension on T2 imaging. None demonstrate perilesional edema. There are no associated developmental venous anomalies.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no mass effect or midline shift. The pituitary gland is normal in size. No diffusion-weighted abnormalities are identified to suggest the presence of acute ischemia. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear.
1.MRI evidence for multiple cerebral cavernous malformations. None demonstrate perilesional edema.2.Encephalomalacia is present involving the anterior right temporal lobe with adjacent gliosis as well as susceptibility abnormality from presumed hemosiderin staining from prior cavernous malformation resection.
