Differential Diagnosis for 14mm Endometrium Thickening

Single Most Likely Diagnosis

  • Endometrial Hyperplasia: This condition is characterized by the excessive proliferation of endometrial cells, leading to thickening of the endometrium. A thickness of 14mm is suggestive of this condition, especially in postmenopausal women.

Other Likely Diagnoses

  • Polyps: Endometrial polyps are growths in the lining of the uterus (endometrium) and can cause thickening. They are common in women of reproductive age but can also occur in postmenopausal women.
  • Fibroids: Uterine fibroids, especially submucosal ones, can cause endometrial thickening due to their location and the potential for associated endometrial hyperplasia.
  • Atrophy: In postmenopausal women, endometrial atrophy is common, but a thickness of 14mm is higher than expected for simple atrophy, suggesting another underlying cause. However, it's still considered due to the age group and potential for co-existing conditions.

Do Not Miss Diagnoses

  • Endometrial Cancer: Although less common, endometrial cancer must be ruled out, especially in postmenopausal women with unexplained endometrial thickening. The risk increases with age, and a thickness of 14mm warrants further investigation.
  • Infection: Pelvic infections can cause endometrial thickening. Although less likely, missing an infection could lead to serious complications, including infertility and chronic pain.

Rare Diagnoses

  • Tamoxifen-Induced Endometrial Changes: Women on tamoxifen therapy for breast cancer can experience endometrial thickening due to the drug's estrogenic effects on the uterus.
  • Metastatic Disease: Rarely, cancers from other parts of the body can metastasize to the endometrium, causing thickening. This would be an unusual presentation but should be considered in patients with a known history of cancer.
