In this radiology lecture, we review the ultrasound appearance of endometrial polyps!

Key teaching points include:

Endometrial polyps are benign hyperplastic overgrowths of endometrial tissue.
Sessile or pedunculated, can cause endometrial thickening.
Often asymptomatic, may cause abnormal uterine bleeding or be associated with infertility.
US appearance: Focal, echogenic, round or ovoid. Often best seen in proliferative phase of menstrual cycle (as opposed to secretory phase) due to increased contrast between echogenic polyp and hypoechoic functional layer of endometrium. May see hypoechoic halo inside margin of endometrium. Usually solid, but can have cystic changes.
By comparison, submucosal fibroids are usually hypoechoic with posterior shadowing.
A feeding vessel/vascular pedicle on color Doppler is 95% specific for endometrial polyp.
Polyps can prolapse into cervix or vagina.
Tx: Polypectomy if symptomatic.
