[Acute sialadenitis by iodine contrast medium administration]

Area of Science:

• Radiology
• Pharmacology
• Otolaryngology

Background:

• Acute iodide sialadenitis is an uncommon adverse effect of iodinated contrast agents.
• The exact cause of this condition remains unknown, but kidney dysfunction may increase risk.

Observation:

• A case study details a 68-year-old male experiencing submandibular salivary gland swelling post-abdominal CT with iodinated contrast.
• The swelling was self-limiting.

Findings:

• Diagnosis is primarily clinical, requiring differentiation from angioedema, infections, and salivary stones.
• No definitive treatment or preventive measures have been established.

Implications:

• Given the frequent use of iodinated contrast in imaging and interventions, awareness of iodide sialadenitis is crucial for clinicians.
• Prompt recognition can help manage patient expectations and avoid unnecessary investigations or treatments.
