Unspecified cerebral artery occlusion with cerebral infarction [434.91], Reason for Study: ^Reason: 72F with h/o CVA with altered mental status History: AMS Redemonstration of restricted diffusion on the left frontal lobe middle and inferior frontal gyri indicating subacute ischemic infarct. The degree of restricted diffusion has been reduced indicating normal evaluation process of acute ischemic infarct. No evidence of hemorrhage transformation.Redemonstration of multifocal chronic ischemic infarct with encephalomalacia involving right frontal lobe, right temporal occipital lobe, left occipital lobe left precuneus. Extensive nonspecific small vessel ischemic lesions, again do not show any significant interval change since prior scan.The ventricles, sulci and cisterns are symmetric and unremarkable. 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.
Evolving right frontal lobe middle and inferior frontal gyri subacute ischemic infarct without evidence of hemorrhagic transformation.No interval change of multifocal chronic ischemic infarct with encephalomalacia since prior scan.No change of extensive nonspecific small vessel ischemic disease.
