Seventy-one postmenopausal patients were enrolled with either EH or EC that had been diagnosed by endometrial biopsy. Patients at greatest risk of developing endometrial hyperplasia include those with a high body mass index (BMI) because of increased aromatase conversion of ovarian androgens in adipose tissue, anovulation due to polycystic ovary syndrome (PCOS) or peri-menopause, or estrogen producing ovarian tumors. Prediction of benign and malignant endometrial disease: hysterosonographic-pathologic correlation.

The most frequent (in 19 from 107 women--17.75%) the cancer was recognized in cases of endometrial hyperplasia, especially when ultrasound image of endometrium was non-homogenous and irregular, and the rarest was in the cases of affirmed fluid in uterine cavity (1 from 22 examined women--4.5%). The presence of cystic spaces is unhelpful and a diagnosis of so-called cystic hyperplasia does not really exist or help in management. The simplified World Health Organization (WHO) definition classifies hyperplasia into two groups, depending on the presence or absence of histologic atypia: The first has a low risk of progressing to become cancer — less than 5 percent over 20 years, according to a Royal College of Obstetricians and Gynaecologists study titled "Management of Endometrial Hyperplasia" — and can be treated medically.

Remember, there is some overlap between what can appear on ultrasound to be a normal endometrial thickness and what is, in reality, an abnormality. vaginal color Doppler ultrasound (TV-CDU) in differentiating between endometrial hyperplasia (EH) and endometrial carcinoma (EC) and in predicting tumor spread in patients with EC. The present study was aimed to compare application of contrast enhanced ultrasound (CEUS) in diagnosis of endometrial carcinoma (EC) and endometrial hyperplasia (EH). Saunders. the inner lining of the uterus, due to hick estrogen stimulation. Transvaginal ultrasound may have a role in diagnosing endometrial hyperplasia in pre- and postmenopausal women.
