Objective: To describe a case report of hydrosalpinx that changed dramatically in size during the menstrual cycle.
Design: Case report.
Setting: University teaching hospital reproductive endocrinology and infertility practice.
Patient(s): A 32-year-old woman with a history of medical and surgical treatments of endometriosis who sought infertility treatment.
Intervention(s): Transvaginal ultrasonography performed sequentially during menstrual cycles.
Main outcome measure(s): Size of hydrosalpinx-like image.
Result(s): The size of the hydrosalpinx-like image in the left adnexal region varied; it peaked during the ovulatory period and then remarkably diminished in a cyclic manner. Laparoscopy revealed a dense adhesion between the left tubal fimbriated end and the posterior uterine wall, which led to terminal obstruction of the tube.
Conclusion(s): Change in the volume of the hydrosalpinx in this case was speculated to reflect the normal tubal fluid production regulated by ovarian hormones.
