Late adverse reactions to iopromide (Ultravist®) diagnosed by the patch test: a case report

=Abstract= Iodinated contrast media (CM) can cause immediate and late reactions. We treated a patient with a recurrent generalized maculopapular rash and a fever that occurred within two days of exposure to iodinated CM, iopromide (Ultravist ® ), for chest computed tomography. We performed skin testing including prick tests, intradermal tests, and patch tests. Our findings indicated a late skin reaction to Ultravist®in addition to cross-reactions to other iodinated CM such as ioversol (Optiray ® ), iohexol (Iobrix ® ), and iobitridol (Xenetix ® ). In this study, we report the case of a patient diagnosed with a late adverse reaction to Ultravist®in addition to cross-reactions to other iodinated CM. (Korean J Pediatr 2009;52:499-503)
