The mechanisms of these reactions and of the sensitization to GBCAs are still largely unknown. We describe four cases of patients who experienced immediate adverse reactions to GBCAs with a demonstrated cutaneous hypersensitivity suggesting an IgE-mediated mechanism.Keywords: gadolinium-based contrast agents, hypersensitivity, IgE-mediated reactions
