21 year old w/ history of myxopapillary ependymoma status post radiation therapy; history of cavernous malformations Redemonstrated are innumerable punctate foci of susceptibility throughout the brain which are not appreciably changed since prior brain. No enlarging lesions are present. No new edema or acute or subacute blood products to suggest new hemorrhage. Prominent hemosiderin staining involving the left precuneus is again seen related to prior hematoma. No evidence of acute infarct. A few nonspecific scattered punctate foci of FLAIR hyperintensity are again seen. No abnormal enhancement. No intracranial mass effect, midline shift, or herniation. Ventricles are normal in size. Visualized calvarium and extracranial soft tissues are grossly unremarkable.
Innumerable foci of susceptibility effect throughout the brain likely related to microhemorrhages from radiation therapy as well as a larger area of hemosiderin deposition in the left precuneus appear similar to prior examination.
