MultiHance as a contrast alternative for Gadovist allergic patients.

The dramatic rise in the use of contrast agents for diagnostic imaging within the last decade has largely contributed to the effectiveness of MR imaging, however even with the use of prophylaxis, adverse reactions to contrast, including anaphylaxis, still occur. We describe the case of a 46-year-old female patient with a hemangiopericytoma requiring ongoing contrast MR surveillance, and a documented anaphylactic reaction to Gadovist (gadobutrol injection) despite premedication. Allergy testing was positive to intradermal undiluted Gadovist, confirming an IgE-mediated Gadovist allergy, with subsequent skin testing by prick and intradermal negative to undiluted MultiHance. She went on to receive MultiHance prior to her subsequent MRI scans without clinical reaction and without premedication, demonstrating that there may be superior alternatives to traditionally used gadolinium dyes in patients with moderate to severe reactions, and warrants further investigation into the anaphylactoid characteristics between the different gadolinium-based contrast agents.
