Somnolence [R40.0], Reason for Study: ^Reason: 74 y/o man w/ a hx of stroke who p/w AMS Motion artifact degraded exam quality.There is no evidence of acute ischemic or hemorrhagic lesion on this scan.There are, however, multiple chronic ischemic infarctions with encephalomalacia including right frontal lobe superior frontal gyrus, right inferior parietal lobule, right temporal and occipital lobes, left inferior parietal lobule and left occipital lobe. There are subtle susceptibility lesions involving right inferior parietal lobule and left occipital lesion indicating prior hemorrhagic conversion.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. 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.2. Multifocal chronic ischemic infarct with encephalomalacia involving bilateral hemispheres.
