Abstract

A patient with maculopapular reactions to iopamidol needed to undergo angiography for a cerebral arteriovenous malformation. In vivo and in vitro tests were performed with ionic and nonionic contrast media, including iopamidol and iobitridol. All results were positive, demonstrating delayed hypersensitivity. The patient received 6-alpha-methylprednisolone and cyclosporine 1 week before and 2 weeks after four angiograms were obtained with the use of iobitridol, which was well tolerated.
