Figure 1: Case 1: (a) Initial magnetic resonance imaging (MRI)-diffusion-weighted images (DWI) show acute ischemic changes in the right parieto-occipital lobe. b) Initial magnetic resonance angiography (MRA) shows right internal cerebral artery (ICA) occlusion. (c) Left internal cerebral angiography shows leptomeningeal collateral flow through the anterior cerebral artery (white arrowheads). (d and e) Right internal cerebral angiography shows occlusion of the petrous portion of the ICA (white arrow) and collateral flow through the ophthalmic artery (white arrow heads). (f) Radiography image shows the percutaneous transluminal angioplasty balloon (white arrow). (g and h) Right internal cerebral angiography shows revascularization of the right ICA with mild stenosis. (i) Posttreatment MRI-DWI show no ischemic change. (j) Posttreatment MRA shows revascularization of the right ICA.
