Atrophy of the endometrium is often a physiological postmenopausal phenomenon where it is more specifically termed post-menopausal endometrial atrophy.
While most patients are asymptomatic, It is one of the commonest cause of post menopausal bleeding, accounting for approximately 75% of cases 1).
Often the atrophic endometrium is associated with cystic dilatation of glands where it is then termed endometrial cystic atrophy 4.
Other factors that can cause endometrial atrophy include
- prolonged oral contraception
- hypo-oestrogenic state : ovarian dysfunction
- Tamoxifen use
To be considered atrophic, the endometrial thickness should measure less than 4 - 5 mm on a transvaginal ultrasound scan. The uterine body to cervix ratio will also tend to decrease and may approach 1 : 1.
May again demonstrate a decrease in endometrial thickness similar to that observed with ultrasound. The junctional zone may no longer be evident.
