Clinical significance of endometrial fluid collections in asymptomatic postmenopausal women

The diagnostic significance of sonographic findings of endometrial fluid collections in the presence of a thin endometrium in postmenopausal women was evaluated by performing routine vaginal ultrasonographic evaluation of pelvic organs. The study included 9 women aged 61 to 79 years who had been postmenopausal for 7 to 30 years, and in whom endometrial fluid collections were incidentally demonstrated. Endometrial samplings followed the ultrasonographic examinations in all 9 patients, and the correlation between the histologic report and the endometrial ultrasonographic thickness was evaluated. Results suggest that endometrial fluid collections found in asymptomatic postmenopausal patients still may be associated with endometrial malignancy, even in the presence of thin endometrium.
