Anaphylactic reaction to MRI contrast agent. / Anafylaktisk reaksjon ved bruk av MR-kontrastmiddel.

BACKGROUND: Magnetic resonance imaging (MRI) is a non-invasive test with a low complication rate even when using contrast agents. Nevertheless, even routine examinations can cause serious complications, as this case illustrates. CASE PRESENTATION: Approximately one minute after receiving an intravenous contrast agent containing gadoteric acid (Dotarem®), a woman suffered a generalised seizure and lost. INTERPRETATION: Anaphylactic shock can occur as a rare complication of MRI with contrast enhancement. The examination should not be performed without a clear indication.
