Definition

Postmenopausal uterine bleeding is bleeding that occurs in a woman whose menstrual periods have ceased for 12 months and has varying causes.

The most common cause is atrophy of the vaginal mucosa or endometrium. However, endometrial cancer causes 10-15% of cases of postmenopausal bleeding.

Structural and functional changes vary depending on cause.

However, the result is always uterine bleeding after menopause, which can resemble menstrual flow, giving women their common clinical presentation.

Diagnosis is based on clinical history, and the evaluation should include endometrial biopsy to rule out endometrial cancer.

Treatment depends on the cause found at evaluation.

Atrophy

Atrophic Endometrium

The transvaginal ultrasound is from a 62 year old post menopausal patient who presents with pelvic discomfort. The ultrasound shows a small atrophied uterus. The myometrium (dark red) junctional zone (light red) and endometrial cavity (pink) are outlined. In the sagittal plane the uterus measures 3.4cms in cranoicaudal dimension by 2.4cms in anteroposterior dimension (a,b) In the axial dimension (c,d) the uterus measures 2.4cms. The endometrial stripe is measured in the sagittal plane and measures .7mms.
