Case in brief

A 75-year-old woman with chronic kidney disease developed painful bilateral submandibular swelling 16 hours after receiving intravenous iopromide for a CT scan. She had a history of similar swelling after prior contrast exposure. Ultrasound revealed enlarged submandibular glands with increased vascularity but no sialolithiasis. Conservative treatment led to complete resolution of symptoms within 4 days.

Diagnostic / clinical pearl

Clinicians should recognize iodinated contrast-induced sialadenitis as a potential delayed reaction, characterized by specific clinical and imaging findings, to prevent misdiagnosis and unnecessary interventions.
