We report a case of successful contrast re-challenge in a 60-year-old female patient who developed CIN after her first procedure of coronary angiography (CAG) which resulted in symptoms of disorientation, amnesia and cortical blindness. A non-contrast enhanced CT performed four hours after the CAG was normal, however, her MRI brain scan showed scattered tiny hyper intensities in posterior occipito-temporal and parietal regions suggesting CIN. Patient\u2019s symptoms resolved completely after 72 hours. Two months later, because of persistent exertional angina, patient was successfully re-challenged with lesser amount of contrast medium with administration of hydrocortisone prior to procedure, and PCI to LAD was completed without recurrence of CIN.\r\ndoi: https:\/\/doi.org\/10.12669\/pjms.36.5.2688\r\nHow to cite this:Sadiq MA, Al Habsi MS, Nadar SK, Shaikh MM, BaOmar HA.
