Summary

A rare side effect of radiocontrast agents, sialadenitis, caused temporary submandibular gland swelling after percutaneous transluminal coronary angioplasty (PTCA). The swelling resolved within 48 hours with no specific treatment needed.

Area of Science:

  • Otolaryngology
  • Radiology
  • Pathology

Background:

  • Sialadenitis, inflammation of salivary glands, can be caused by various factors.
  • Radiocontrast agents are commonly used in medical imaging procedures like PTCA.
  • Adverse reactions to radiocontrast agents, though rare, are important to document.

Observation:

  • A 63-year-old woman presented with acute swelling of the submandibular glands.
  • The swelling occurred shortly after undergoing percutaneous transluminal coronary angioplasty (PTCA).
  • An otolaryngologist initially suspected viral sialadenitis.

Findings:

  • The submandibular gland swelling resolved spontaneously within 48 hours.
  • Sialadenitis is identified as a rare, self-limited side effect of both ionic and nonionic radiocontrast agents.
  • The exact pathogenic mechanism underlying this reaction remains unknown.

Implications:

  • This case highlights sialadenitis as a potential, albeit rare, complication following procedures involving radiocontrast agents.
  • The condition has an excellent prognosis and does not require specific therapeutic intervention.
  • Further research into the pathogenic mechanisms of radiocontrast-induced sialadenitis may be warranted.
