Disorientation, unspecified [R41.0] / Personal history of transient ischemic attack (TIA), and cerebral infarction without residual deficits [Z86.73], Reason for Study: ^Reason: AMS, h/o ?recent CVA History: AMS Redemonstration of prior craniotomy with metastatic colon cancer resection on the left frontal lobe superior frontal gyrus and adjacent encephalomalacia, no change since prior scan.Localized encephalomalacia of the left occipital lobe, no change since prior scan.Underlying brain shows extensive patchy high signal intensity lesions on bihemispheric periventricular white matter, likely related to prior treatment, no change since prior scan.Multifocal various sized bihemispheric susceptibility lesions on gradient echo images indicating possible prior radiation therapy related are again seen, no change since prior scan.There is no evidence of abnormal enhancement.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, restricted diffusion/acute ischemia, or abnormal contrast enhancement. 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.
1. No evidence of acute ischemic or hemorrhagic lesion. No abnormal enhancement.2. No change of multifocal encephalomalacia, non specific white matter lesions and susceptibility lesions since prior scan.
