Iodide mumps can occur after administration of any iodinated contrast media, irrespective of the osmolality of the contrast preparation. This condition is characterized by acute salivary gland swelling shortly after contrast study, presumably secondary to toxic accumulation of iodide in salivary glands with high iodide concentration. In this article, a case of iodide mumps is presented, along with a discussion of vulnerability due to renal impairment, which causes prolongation of the half-life of contrast media. A total of 30 additional cases of iodide mumps published in the English literature were reviewed. Despite the clinical observations that iodide mumps resolved with conservative management, it should be emphasized that recurrence is common if vulnerable patients are subjected to further iodinated contrast media.
