Several types of brain injury incurred during carotid artery stenting (CAS), such as embolic injury, hemodynamic events, and hemorrhage. Rapid differential diagnosis is important for decision making, and may help to avoid subsequent complications. Here, we describe a case with severe triple vessel coronary artery disease, who underwent right coronary artery (RCA) stenting and ad hoc left CAS. Patient developed neurological deficit two hours after the procedure. Brain computed tomography (CT) revealed diffuse cortical enhancement similar to subarachnoid hemorrhage (SAH). Patient recovered dramatically with complete resolution of contrast enhancement after four days of conservative treatment, final diagnosis was a rare reported case of transient contrast encephalopathy. © 2008 Wiley‐Liss, Inc.
