Disorientation, unspecified [R41.0] / Other abnormalities of gait and mobility [R26.89], Reason for Study: ^Reason: eval for interval change, ischemic disease, mass, NPH History: loss of time, confusion, gait impairment No evidence of acute ischemic or hemorrhagic lesion on this scan.Patchy confluent FLAIR/T2 high signal intensity lesions on bilateral periventricular white matter and centrum semiovale indicating likely non specific small vessel ischemic disease are seen with more involved of the left hemisphere comparing to those of the right, unchanged since prior scan.The ventricles, sulci and cisterns are 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.
1. Extensive confluent white matter lesions of bilateral hemispheres (left worse than right) likely indicating non specific small vessel ischemic disease, unchanged since prior scan.2. No evidence of acute ischemic or hemorrhagic lesion.
