Summary

Uterine artery embolization (UAE) for fibroids may mask sarcomas. Pre-procedure risk assessment including clinical and imaging findings is crucial to avoid delayed diagnosis and treatment of uterine malignancies.

Area of Science:

  • Gynecologic Oncology
  • Interventional Radiology
  • Reproductive Medicine

Background:

  • Uterine artery embolization (UAE) is a common conservative treatment for uterine fibroids.
  • Rare instances of sarcoma diagnosis shortly after UAE highlight a potential diagnostic challenge.
  • The necessity of enhanced pre-procedural screening for malignancy before UAE remains under investigation.

Observation:

  • A 45-year-old patient developed progressive symptoms six months post-UAE for symptomatic uterine fibroids.
  • Subsequent surgery revealed an endometrial stromal sarcoma, indicating a missed diagnosis prior to embolization.
  • This case underscores the potential for UAE to obscure or delay the diagnosis of uterine sarcomas.

Findings:

  • Current diagnostic work-up prior to UAE may not be sufficient to rule out underlying malignancies.

  • Malignant conditions like endometrial stromal sarcoma can be mistaken for or masked by uterine fibroids.
  • Delayed diagnosis of sarcoma due to UAE can lead to significant delays in definitive oncologic treatment.

    • Implications:

    • Implementing a more rigorous risk assessment for malignancy before UAE is essential.
    • Clinical symptoms, physical examination, and advanced imaging should be carefully evaluated to identify high-risk patients.
    • This approach aims to prevent the delay of critical sarcoma treatment and improve patient outcomes.
