Cerebral infarction, unspecified [I63.9] / Other amnesia [R41.3], Reason for Study: ^Reason: right subcortical stroke, memory difficulties History: as above. There is no evidence of acute ischemic or hemorrhagic lesion on the scan.There is encephalomalacia on the right basal ganglia with the susceptibility artifacts indicating prior hemorrhagic infarct.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Right basal ganglia chronic hemorrhagic infarction with encephalomalacia.No acute ischemic or hemorrhagic lesion on this scan.
