(A and B) Immediate head CT after deterioration of neurological symptoms shows hyperdense lesions with mild space-occupying effect in the left basal ganglia and both lateral ventricles. (C and D) Follow-up CT after 5 h shows significant resolution of hyperdense lesions and and hyperdensity of the right upper insula. (E and F) Two days later, CT shows almost complete resolution of hyperdense lesions in the lateral ventricles and a small of amount residue in the basal ganglia and insular, without obvious surrounding edema and mass effect. (G and H). At eight days after intravenous thrombolytic treatment, CT shows only some scattered small petechiae in the left infarcted area
