Extravasation cyst of salivary gland

Last edited: 4/15/2026

Overview

Extravasation cysts of salivary glands, often related to intravenous contrast medium administration, involve leakage of fluid into surrounding tissues, potentially causing localized swelling and discomfort without necessarily progressing to severe complications 1.

Diagnosis

  • Clinical Presentation: Primarily diagnosed based on clinical symptoms and imaging findings 1.
  • Imaging: Contrast-enhanced imaging may help identify the extent of extravasation 1.
  • Grading: Not specifically detailed; severity often assessed clinically 1.
  • Management

  • Initial Management: Supportive care including elevation, cold compresses, and monitoring for infection 1.
  • Referral Criteria: Referral to surgical intervention based on clinical severity rather than volume of extravasated material 1.
  • Pharmacological Interventions: No specific drug classes or doses mentioned for extravasation cysts of salivary glands 1.
  • Special Populations

  • Pregnancy: No specific guidelines provided in the abstract 1.
  • Pediatrics: No specific guidelines provided in the abstract 1.
  • Elderly: No specific guidelines provided in the abstract 1.
  • Comorbidities: Management considerations for comorbidities not detailed; clinical severity remains the primary guide 1.
  • Key Recommendations

  • Risk assessment for extravasation should consider scanning technique and patient-specific risk factors (Evidence: Moderate) 1.
  • Diagnosis relies heavily on clinical evaluation, with imaging used to assess extent (Evidence: Moderate) 1.
  • Surgical referral should be based on clinical severity rather than the volume of extravasated material (Evidence: Expert opinion) 1.
