Posterior reversible encephalopathy syndrome following coronary angiography.

Posterior reversible encephalopathy syndrome (PRES) is a relatively rare neurotoxic disorder. Our patient was a 56-year-old male who underwent an elective coronary angiography. Few hours postprocedure, the patient developed bilateral painless vision loss, headache, vomiting and hypertension and was subsequently diagnosed with PRES. Possible trigger factors could be contrast agent used, or hypertension. Contrast agent-induced PRES in hypertensive patients is benign and reversible, and a high-grade suspicion about this possibility is critical for precise management. Our patient was successfully treated with supportive management and was doing well on follow-up.
