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.
