Clinical value of endometrial thickness
An endometrial thickness < 5 mm almost excludes the risk of malignancy in cases of postmenopausal bleeding. However a figure up to 8 mm could be normal in obese women, patients on HRT and hypertensive women taking calcium channel blockers. A thick endometrium in non-symptomatic postmenopausal women should not indicate invasive treatment as bleeding is usually the first symptom of malignancy. Such thick endometrium could be due to an end prom party wears specially for thick waist ... ometrial polyp as an example. At the same time endometrial thickness does not carry the same diagnostic weight of sinister pathology in younger symptomatic women within their reproductive age as for postmenopausal ones.
In summary endometrial pathology could be reflected by one of the following findings:
> 5 mm thick endometrium at the end of menstruation,
abnormaly thick endometrium > 13 mm at other times of the cycle,
abnormally thin endometrium at midcycle,
irregular endometrial / myometrial interface,
indiscriminate endometrial outline,
heterogenous endometrial texture.
The presence of fluid in the uterine cavity could be seen in the following conditions:
during menstruation,
during super-ovulation,
incomplete miscarriage,
cervical stenosis,
endometritis with irregular heterogenous endometrium,
cervical or endometrial cancer.
