Overview
Endometrial hyperplasia must be differentiated from conditions that have similar ultrasound appearances such as normal thickening during the secretory phase, sessile endometrial polyp, submucosal uterine fibroids, endometrial cancer, adherent intrauterine blood clot,and pregnancy.[1][2][3]
Differential Diagnosis
- Endometrial hyperplasia must be differentiated from the following conditions that have abnormal thickening of the uterus:[1][2][3]
- Early pregnancy prior to sac being visualized (<5 weeks of gestation)
- Ectopic pregnancy (thickened endometrium and sometimes fluid collection or pseudogestational sac can be associated)
- Retained products of conception (heterogeneously thickened endometrium with increased vascularity)
- Adherent intra-uterine blood clot (heterogeneous endometrium with no vascularity)
- Molar pregnancy thickened with multiple small cystic spaces
- Endometritis (prominent hyperechoic endometrium with of without fluid and debris)
- Endometrial carcinoma (variable appearance)
- Endometrial polyp or polyps (usually hyperechoic, often focal, look for vascular stalk)
- Submucosal uterine fibroids
- Intrauterine adhesions (irregular echogenic areas with focal thickening)
