Contrast Induced Sialadenitis of the Submandibular Glands Case Report and Review of the Literature

Contrast-induced sialadenitis, often referred to as “iodide mumps,” is a rare but well-documented adverse reaction associated with the intravenous administration of iodinated contrast media. Characterized by an acute, painless and transient swelling of the salivary glands most frequently the parotid glands iodide mumps remains a benign condition that generally resolves spontaneously within a short period. Although the exact pathophysiology is not fully understood, several hypotheses have been proposed, including hypersensitivity reactions, toxic glandular edema, or transient obstruction of the glandular ducts. As the use of computed tomography (CT), angiography, and other imaging modalities requiring iodinated contrast continues to grow, it becomes increasingly important for radiologists and clinicians to recognize this condition. Understanding its presentation, diagnostic approach, management strategies, and prognosis helps ensure that patients receive appropriate care, are spared unnecessary investigations, and benefit from timely reassurance
