Hello, Good Day. Normally the post menopausal endometrium is atrophic and should measure within 4 mm in thickness. In your case it is mild increased in thickness. And the finding of trace fluid versus tiny cyst
are both abnormal. Had you undergone transvaginal scan? That will show the picture more clearly. Anyway as you had some past history of disease, you should consult your gynaecologist with all your past medical documents and follow here advise. You should not delay this. All the best. take care.
