Iodide mumps, a swelling of the salivary glands after iodinated contrast dye, is usually described as harmless and short-lived. But a 37-year-old woman's glands swelled so severely after a brain-vein procedure that she needed a breathing tube and a ventilator for three days.
The case report in the American Journal of Case Reports, by a University of Wisconsin–Madison neurologist and a colleague, was published online in February. It is one of several reports on the condition this year, including one that followed facial iodine iontophoresis, a treatment that uses electric current to push iodine through the skin. Its authors argue the reaction is likely underreported and that clinicians should keep it in mind when a patient's neck swells after a contrast procedure.
