A susceptibility vessel sign (arrow) was present on T2* sequence in the right supraclinoid ICA, seen as a dramatic signal loss by comparison with contralateral ICA (dotted arrow). Clot of the basilar tip (arrow) and the left P1 segment (dotted arrow) seen on catheter angiogram (frontal projection, C). A susceptibility vessel sign (D) was seen in the same locations (basilar tip, arrow and P1 segment, dotted arrow).
