A complete resolution of sialadenitis induced by iodine containing contrast with intravenous dexamethasone infusion.

Salivary gland enlargement following the administration of iodine is an extremely rare event, and the pathophysiology of iodine-induced sialadenitis is not yet fully known. The onset of symptoms can start within a few minutes to five days after contrast administration. The course of iodine-induced sialadenitis is extremely benign, and rapid resolution of symptoms is expected without treatment. We report the case of a 59-year-old white female who noted mildly painful swelling involving the right side of her face within five days of receiving intravenous iodine-containing contrast. A diagnosis of iodine-related sialadenitis was made. She was given 20 mg of decadron intravenously, with prompt resolution of the swelling within a few hours.
