Aphasia [R47.01], Reason for Study: ^Reason: stroke History: slurred speech, R face and R arm wkness There are restricted diffusion areas on the left basal ganglia, internal capsule genu and posterior limb which extend cranially to the level of centrum semiovale indicating acute/subacute ischemic infarct. There is no evidence of hemorrhagic conversion.Scattered FLAIR/T2 high signal intensity lesions on periventricular bihemispheric white matter are seen, indicating nonspecific small vessel ischemic lesions.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. 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. Fluid collection with ovoid well circumscribed low signal intensity lesion is seen at sphenoid sinus indicating focal accumulation of high protein content secretion.
1. Left basal ganglia, internal capsule and centrum semiovale acute ischemic infarct without evidence of hemorrhagic transformation.2. Underlying nonspecific small vessel ischemic disease.
