Evaluate for septic embolic infarction, subacute: subtle right face, arm motor deficit, and MSSA mitral valve endocarditis. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is encephalomalacia in the left anterior frontal lobe. There are also subcentimeter foci of T2 hyperintensity in the left basal ganglia and right corona radiata. In addition, there are a few nonspecific scattered foci of t2 hyperintensity in the cerebral white matter. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is a right sphenoid sinus retention cyst. There is nonspecific scattered fluid signal in the left mastoid air cells.
Chronic left anterior frontal lobe infarct. Subcentimeter lesions in the left basal ganglia and right corona radiata also likely represent chronic lacunar infarct. No evidence of acute intracranial hemorrhage, mass, or acute infarct.
