Migrating susceptibility vessel sign in posterior circulation stroke

A 95-year-old woman with atrial fibrillation was admitted with acute onset of disturbed consciousness. On admission, neurological deficits rapidly improved and completely disappeared. The prothrombin time-international normalized ratio (PT-INR) was 1.4 although she was medicated with warfarin (2.5 mg/day). Brain magnetic resonance (MR) imaging with diffusion-weighted imaging (DWI) findings on admission were normal, but MR angiography (MRA) detected basilar-top occlusion and susceptibility-weighted imaging (SWI) confirmed the susceptibility vessel sign at the basilar top (Fig.
