Transient contrast neurotoxicity is a rare but well-recognized complication of angiography that is due to neurotoxicity of the contrast agent. Patients with renal dysfunction may be inclined to develop contrast medium neurotoxicity due to delayed elimination of the contrast medium in renal metabolism. In this report, we present an unusual case of transient neurotoxicity in a patient with severe chronic kidney disease following percutaneous coronary intervention mimicking clinically and radiologically subarachnoid hemorrhage. The patient’s clinical symptoms improved rapidly and fully recovered after hemodialysis and conservative treatment. We believe that performing early hemodialysis is an effective treatment to improve symptoms in end-stage renal disease patients with contrast-induced encephalopathy.
