Subsequently, he underwent cerebral angiography that showed multiple fractures in the stent and a small metallic image in the topography of a branch of the right lingual artery, which is suggestive of a fragment thereof [Figure 1].

Two small metallic images were evident in the topography of branches of the right middle cerebral artery as well, which was also suggestive of stent fragments [Figure 2].
