Summary
Distinguishing uterine polypoid adenomyoma (PA) from endometrial polyps (EP) is challenging. An ultrasound-based nomogram effectively differentiates PA from EP, aiding clinical decisions.
Area of Science:
- Gynecology
- Diagnostic Imaging
- Pathology
Background:
- Uterine polypoid adenomyoma (PA) poses risks of persistence, recurrence, and malignancy.
- Preoperative differentiation between PA and endometrial polyps (EP) is clinically challenging, impacting treatment.
- Accurate diagnosis is crucial for appropriate patient management.
Purpose of the Study:
- To compare clinical and ultrasonographic features of PA and EP.
- To develop a predictive nomogram for accurate preoperative diagnosis of PA versus EP.
Main Methods:
- Retrospective analysis of 52 PA and 52 EP cases.
- Extraction of demographic, clinicopathological, ultrasound, and surgical data.
- Logistic regression and ROC curve analysis for nomogram development and validation.
Main Results:
- PA patients were older, more frequently postmenopausal, and reported more postmenopausal bleeding than EP patients.
- Significant ultrasound differences included lesion multiplicity, diameter, morphology, echogenicity, cystic components, and vascularity.
- The developed nomogram, using 4 ultrasound parameters, achieved an AUC of 0.930 for distinguishing PA from EP.
Conclusions:
- PA and EP possess distinct clinical and ultrasound characteristics.
- The ultrasound nomogram shows significant discriminative power for differentiating PA from EP.
- Further multi-center validation is recommended to confirm the nomogram's clinical utility.
