An adverse reaction following sialography.

Abstract
Reactions following the administration of iodine are well documented in general radiography, but are unusual following sialography. A patient who experienced an adverse reaction following sialography with an iodine-based, low osmolar, contrast medium, Hexabrix 320, is presented. The reaction consisted of severe shoulder and back pain 24 h after the procedure. A skin rash was identified involving the right axilla, groin and elbow, with swelling visible around the right elbow joint. It was not possible to distinguish, on the basis of the available evidence, between an anaphylactoid and idiosyncratic allergic reaction.
