A case of acute bilateral iodine‐induced submandibular sialadenitis: Ultrasound findings

Abstract

Acute sialadenitis is a rare adverse reaction to iodine-based contrast agents. Ultrasound (US) is usually the preferred imaging method to evaluate the salivary glands; along with clinical and anamnestic data, US allows the diagnosis of contrast-induced sialadenitis. We present a case of acute bilateral submandibular sialadenitis induced by intravenous administration of iodine-based contrast media for a contrast-enhanced computed tomography scan diagnosed by US.
