Presentation
Left sided weakness. History of atrial fibrillation.
Patient Data
Loss of grey white matter differentiation involving the right frontal lobe superior sulcus near the vertex is keeping with subacute infarction involving the anterior cerebral artery territory. No territorial infarction is seen elsewhere in the brain. No intracranial hemorrhage.
There has been expected evolution of the previously demonstrated right sided anterior cerebral artery territory infarct, with progressive hypodensity, swelling and small petechial regions of increased density consistent with blood product but no large hemorrhagic transformation.
Case Discussion
Shows typical features of subacute infarct in the anterior cerebral artery territory with further evolution. The underlying cause was thought to be cardio-embolic given the history of atrial fibrillation (AF).
