Overview
Differential Diagnosis
- Endometrial hyperplasia must be differentiated from the following which have similar appearances on an ultrasound:[1]
- 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)
- Polycystic ovaries (usually uniformly hyperechoic and tends to be diffuse)
- Endometrial polyp (usually hyperechoic, often focal, look for vascular stalk)
- Tamoxifen related endometrial changes (variable appearances)
- Hormone replacement therapy (HRT) in postmenopausal female
- Intrauterine adhesions (irregular echogenic areas with focal thickening)
- Ovarian tumours associated with endometrial thickening
- Endometrioid carcinoma of the ovary
- Granulosa cell ovarian cancer
- Normal thickening during the secretory phase
- Sessile endometrial polyp or polyps (may contain cystic spaces)
- Submucosal uterine fibroids
- Endometrial cancer
- Pregnancy (uterine as well as ectopic)
- Endometrial hyperplasia must also be differentiated from the following:
