Endometrial carcinoma in a post-menopausal woman with atrophic endometrium and intra-cavitary fluid: a case report.

Measurement of endometrial thickness by vaginal ultrasonography is used to detect post-menopausal women at risk for endometrial pathology. The efficacy of this procedure is doubtful in cases of intrauterine fluid accumulation, which is a common finding in this population. We present a case of endometrial carcinoma in an asymptomatic, post-menopausal woman with ultrasonographic imaging of an atrophic endometrium and intra-cavitary fluid. It may be suggested that, in a case of intrauterine fluid accumulation (IFA), endometrial biopsy should be performed regardless of the sonographic endometrial thickness, since the fluid may increase the intracavity pressure and can mask endometrial pathology.
