Summary

Ultrasonography accurately diagnoses adenomyosis by correlating ultrasound features with histology. Specific findings like subendometrial striations improve diagnostic accuracy.

Area of Science:

  • Gynecologic imaging
  • Diagnostic accuracy studies
  • Pathology correlation

Background:

  • Adenomyosis diagnosis relies on characteristic ultrasonographic (US) features.
  • Histologic confirmation is the gold standard but invasive.
  • Accurate non-invasive diagnostic methods are crucial for patient management.

Purpose of the Study:

  • To assess the accuracy of US features for diagnosing adenomyosis.
  • To correlate US findings with histologic results.
  • To evaluate inter- and intraobserver agreement for US assessments.

Main Methods:

  • 102 hysterectomy specimens underwent water bath ultrasonography.
  • Two radiologists independently reviewed US videos, blinded to clinical and histologic data.

  • Specific US features were evaluated and correlated with final histopathology.

    • Main Results:

    • Adenomyosis prevalence was 29.4%.
    • Overall diagnostic accuracy for adenomyosis was 74% (sensitivity 81%, specificity 71%).
    • Subendometrial striations, echogenic nodules, and asymmetric myometrial thickness showed higher specificity and positive predictive value.

    Conclusions:

    • Specific US findings significantly enhance diagnostic specificity for adenomyosis.
    • Ultrasonography is a valuable tool for adenomyosis diagnosis when key features are present.
    • Good intraobserver and moderate interobserver agreement support US utility.
