Pneumoparotitis, a rare cause of parotid enlargement, occurs when air refluxes into the parotid gland via Stensen's duct. This case highlights its link to repeated Valsalva maneuvers for middle ear autoinflation.

Area of Science:

  • Otolaryngology
  • Radiology
  • Medical Imaging

Background:

  • Pneumoparotitis is an uncommon condition characterized by air entering the parotid gland.
  • It results from retrograde airflow through Stensen's duct into the salivary gland acini.
  • This can lead to parotid enlargement and discomfort.

Observation:

  • A patient presented with parotid enlargement attributed to pneumoparotitis.
  • The condition followed a history of frequent autoinflation of the middle ears using the Valsalva maneuver.
  • Clinical presentation and diagnostic imaging were key to the diagnosis.

Findings:

  • Radiographic, sialographic, and ultrasound imaging were utilized to assess the parotid gland.
  • These modalities confirmed the presence of air within the parotid gland structures.

  • The findings correlated with the patient's history of Valsalva maneuver use.

    • Implications:

    • This case underscores the potential link between the Valsalva maneuver and pneumoparotitis.
    • It highlights the importance of considering iatrogenic causes for parotid enlargement.
    • Diagnostic imaging plays a crucial role in identifying air within the salivary glands, aiding in diagnosis and management.
