Overview
Pelvic ultrasound on days 5 to 10 of menstrual cycle reduce the variability in endometrial thickness and may be helpful in the diagnosis of endometrial hyperplasia. On pelvic ultrasound, endometrial hyperplasia is characterized by a homogeneous increase in the endometrial thickness in the majority of patients. However, endometrial hyperplasia may also cause asymmetric or focal thickening with surface irregularity which should raise a suspicion for malignancy.[1]
Ultrasound
- Pelvic ultrasound on days 5 to 10 of menstrual cycle reduce the variability in endometrial thickness and may be helpful in the diagnosis of endometrial hyperplasia.
- The ultrasound appearance can be non-specific and may not be reliable to differentiate between hyperplasia and carcinoma.[2]
- The pelvic ultrasound shows a homogeneous increase in the endometrial thickness. However, endometrial hyperplasia may also cause asymmetric or focal thickening with surface irregularity which should raise a suspicion for malignancy.[1]
- On pelvic ultrasound, endometrial hyperplasia is characterized by:[1]
- An endometrial thickness of >15 mm is considered above normal during the secretory phase of menstrual cycle
- An endometrial thickness of >5 mm is considered abnormal
Tamoxifen associated endometrial changes
- On pelvic ultrasound, tamoxifen induced endometrial hyperplasia is characterized by thickened, irregular, and cystic endometrium.
- Changes tend to be subendometrial in location and may cause subendometrial cysts.[3]
- The degree of endometrial thickening corresponds to the duration of tamoxifen therapy.[3]
