[A case of anaphylactic shock following the administration of Gd-DTPA].

We experienced a case of serious adverse reaction following the administration of Gd-DTPA (gadolinium with diethylenetriamine pentaacetic acid). The patient showed sneezing and hoarseness when Gd-DTPA was administered for the first time. At the second injection, when hydrocortisone was used in advance to prevent allergic reaction, she lapsed into a pre-shock state and anaphylactic reaction was strongly suggested by the laboratory data. The possibility that Gd-DTPA may cause the severe side effects must be noted.
