Iodide mumps: A rare complication of iodine-containing contrast after coronary angioplasty

Exposure to iodine-containing contrast may have some side effects, of which anaphylactoid reaction is a common effect; however, other adverse effects are uncommon (1). Iodide mumps is a rare complication that occurred after the administration of intravascular iodine-containing contrast. This complication introduced painless swelling in bilateral or unilateral submandibular or sublingual glands (1, 2). The true incidence of this adverse reaction remains unclear and some researchers believe that it may be underdiagnosed (3). However, a study has reported that the incidence is nearly 1%–2% (4). We herein report a rare case of iodide mumps following coronary angioplasty where the patient suffered from this complication.
