A 75-year-old woman in Thailand told her care team that CT contrast dye had once made her neck swell, so she was given steroid pills before her next scan. The precaution did not prevent a repeat. Sixteen hours after the injection, painful swelling developed beneath both sides of her jaw.
The case, published Sept. 12 in the American Journal of Case Reports, comes from two radiologists at Ramathibodi Hospital, Mahidol University, in Bangkok. It describes a recurrence of iodinated contrast-induced sialadenitis, an inflammation of the salivary glands after exposure to iodine-based contrast agents, better known as "iodide mumps."
