Abstract

Contrast-induced sialadenitis (CIS) is a rare, benign condition characterized by painless salivary gland swelling after iodinated contrast administration. A 60-year-old man developed bilateral neck swelling 14 hours post-contrast-enhanced computed tomography (CT). CIS was diagnosed based on characteristic ultrasonographic findings, namely, salivary gland enlargement with increased blood flow, which resolved spontaneously within three days. Despite corticosteroid premedication before a subsequent contrast-enhanced CT four months later, similar symptoms recurred. The effectiveness of corticosteroids in preventing CIS remains uncertain. This case highlights the potential for CIS recurrence and the need for further investigation to establish optimal management and preventive strategies.
