Anaphylaxis against gadolinium based contrast agents (GBCAs) has been reported in all severity grades but is less frequent than hypersensitivity/allergy against iodinated contrast materials. Once a patient acquires such an adverse reaction a life-long premedication is usually the consequence in concert with GBCA-enhanced MR-imaging procedures. The usefulness of this prophylaxis has been questioned, and discussed controversially during the past. The herein presented case may shed some light into the dynamic of contrast-medium-induced hypersensitivity reactions.
