Recurrent iodine contrast induced sialadenitis: Case report

Iodine induced sialadenitis is an uncommon condition, induced by exposure to iodine-containing contrast material. Although the condition had been reported in the past, the incidence and pathogenesis of this condition is not well understood, and is thought to be caused by either toxic damage from accumulation of iodine in the salivary glands and ducts, or from renal damage leading to iodine excretion disorder. We present a case of a patient with three separate events of parotid enlargement in reaction to iodine contrast material exposure.
