Other specified health status [Z78.9], Reason for Study: ^Reason: eval for acute cerebral infarction History: acute on chronic aphasia concerning for stroke There are multifocal restricted diffusion lesions on the left MCA territory including left frontal lobe middle and inferior frontal gyri and left posterior parietal lobe indicating acute to subacute ischemic infarction.Underlying brain shows multifocal patchy FLAIR high signal intensity lesions involving bilateral frontal and parietal lobes (left more than right), as well as right occipital lobe and left temporal lobe with encephalomalacia indicating chronic ischemic infarction.Multifocal scattered FLAIR high signal intensity lesions on bilateral periventricular white matter indicating non specific small vessel ischemic disease.Due to patient motion, gradient-echo sequence was not applied therefore, precise evaluation regarding hemorrhagic lesion is incomplete.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, or midline shift. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.There is a retention cyst on the right maxillary sinus.Left eye lens signal is not seen indicating prior cataract surgery.
1. Left MCA territorial acute/subacute ischemic infarctions as described above.2. Multifocal bihemispheric chronic ischemic infarctions with encephalomalacia.
