a Magnetic resonance imaging of the axial brain with diffusion restriction (similar distribution on apparent diffusion coefficient imaging, not shown) involving the corona radiata (red arrow) consistent with ischemia. b Prominent blooming susceptibility artifact within the region of the right middle cerebral artery bifurcation compatible with thrombus (red arrow). c Right carotid injection on cerebral angiogram with abrupt occlusion of the M1 arterial segment of the right middle cerebral artery consistent with thromboembolism (red arrow). d Recanalization of the occluded vessel after mechanical thrombectomy.
