The terms “immediate” and “delayed” adverse reactions induced by contrast media (CM) refer to the reactions' onset but do not provide substantial information concerning the clinical manifestation, the potential risk factors, the treatment modalities, or prevention. Because a variety of different reactions caused by different pathophysiological mechanisms may arise immediately or be delayed after CM injection, and because these need different management, the aim of the present paper is to present the clinical features and to exactly characterize lesser-known cutaneous reactions. A thorough knowledge of the clinical features, their adequate treatment, and, possibly, the subsequent diagnostic procedure for preventing recurrence after reexposure to CM would improve patient management.
