a DWI demonstrated no acute diffusion lesions. b TTP maps showed reduced flow throughout the right MCA field, with substantial mismatch. c Emergent cerebral angiography demonstrated almost complete occlusion of the right ICA with extensive collateral flow via meningeal branches and retrograde ophthalmic flow to the supraclinoid ICA. d DSA after successful angioplasty and stenting of the proximal right ICA revealed minimal residual stenosis and restoration of the antegrade flow of the right ICA.
