Contrast-induced encephalopathy (CIE) is a rare complication of angiography. Presently reported is the case of a patient diagnosed with CIE following peripheral angioplasty with the non-ionic contrast agent, iohexol. A 66-year-old male patient described intermittent claudication and peripheral arterial disease was suspected. Lower extremity angiography was performed, and following dilation of a 7.0x150-mm balloon, a 9.0x57-mm stent was placed in the lesioned vessel. The patient subsequently developed confusion and cortical blindness, and a seizure occurred 1 hour after the procedure. An emergency cerebral computed tomography scan did not reveal any signs of intracerebral hemorrhage. The neurological symptoms disappeared within 24 hours after hydration and sedative medication. CIE was diagnosed based on the patient`s clinical course findings and cerebral imaging.
