A total of 81 patients with EC and simple EH were selected in this study. Endometrial hyperplasia is characterized by a thickening of the endometrium that is more than the typical pre and post-menstrual build up of endometrial tissue. 2. Usually, there is a homogeneous smooth increase in endometrial thickness, but endometrial hyperplasia may also cause asymmetric/focal thickening with surface irregularity, an appearance that is suspicious for carcinoma.

If any fluid is present in the cavity, it should be subtracted from the measurement. 8. 2012;19 (5): 562-71. 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. As a classic 1994 report by Dr. Steven Goldstein stated, "Look at the doughnut rather than the hole." Spectrum of endometrial hyperplasia and its mimics on saline hysterosonography. Endometrial hyperplasia is a histologic diagnosis often made after sampling an endometrium that appears thickened on pelvic ultrasound. The presence of cystic spaces is unhelpful and a diagnosis of so-called cystic hyperplasia does not really exist or help in management. METHODS. Ultrasound Findings. Transvaginal ultrasound is critical for assessing the endometrium and determining whether it appears homogeneous or nonhomogeneous, uniform or nonuniform. A non-linear midline is also an indication of endometrium pathology (Van den Bosch et al., 2021). The first step in determining if you have hyperplasia is a pelvic and transvaginal ultrasound, which evaluates the thickness of the endometrium. One of the major concerns is the potential malignant transformation to endometrial carcinoma. When a patient presents with abnormal bleeding and you are concerned about endometrial hyperplasia, do you immediately biopsy or do you first turn to ultrasound? The objective is to identify the utility of ultrasound as a screening test for endometrial hyperplasia and cancer in an "at risk" cohort. Palmer J, Perunovic B, Tidy J. 12.

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. Therefore, any patient who develops bleeding while taking tamoxifen requires evaluation. For appropriate assessment of endometrial hyperplasia during transvaginal ultrasound, the International Endometrial Tumor Analysis group (IETA) guidelines suggest measuring endometrial thickness in the sagittal plane, at the thickest portion perpendicular to the endometrial midline that includes the anterior and posterior endometrial layers. The presence of cystic spaces is unhelpful and a diagnosis of so-called cystic hyperplasia does not really exist or help in management. 15.

Direct visualisation and biopsy of the uterine cavity using hysteroscopy should be undertaken where Some cases of endometrial hyperplasia, especially atypical, can progress to endometrial cancer, so it is important to study the two together.Endometrial cancer is the most common gynecological cancer in … vaginal bleeding). Seventy-one postmenopausal patients were enrolled with either EH or EC that had been diagnosed by endometrial biopsy. There are several types of endometrial hyperplasia, which include: Hyperplasia can be also classified into two broad groups 5: Unopposed estrogen stimulation (either from an endogenous or exogenous source) is implicated in its pathogenesis; some of these conditions include: Imaging the endometrium on days 5-10 of a woman's cycle reduces the variability in endometrial thickness. ISBN:1416031219. The behavior of endometrial hyperplasia: a long-term study of “untreated” hyperplasia in 170 patients. Endometrial hyperplasia most often is caused by excess estrogen without progesterone.

The sonographic appearance of endometrial hyperplasia is a heterogeneous thickening of the endometrial echo (lining). You may also detect a focal abnormality or the presence of masses, which could lead you to triage the patient to hysteroscopy next rather than biopsy. While histologic evaluation is critical, ultrasound imaging has an equally important role in the evaluation of abnormal uterine bleeding, which is the most common presentation in a woman with endometrial hyperplasia. 4 Ultrasound Features The typical features of endometrial hyperplasia and polyps can be explained by the use of the IETA terminologies.

There are four types of endometrial hyperplasia. 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.
