Contrast-induced encephalopathy after primary percutaneous coronary angioplasty mimicking a subarachnoid hemorrhage

Contrast-induced encephalopathy (CIE) is a rare temporary phenomenon after intravenous injection of contrast media. The prognosis is generally good. Neurological symptoms develop within hours and resolve spontaneously over days. Global syndromes such as confusion can also be seen with cortical and subcortical deficits. There is a good correlation between the volume of contrast extravasation and clinical picture. In addition, this extravasation can be confused with intracranial hemorrhage in the early stage with imaging. In this case, we presented a 62-year-old male patient who developed CIE after coronary angioplasty mimicking subarachnoid hemorrhage and spontaneously recovered on the 2nd day of the event.
