Clomiphene citrate-induced follicular development in the presence of an ovarian ectopic pregnancy.

OBJECTIVE

To describe a case of a patient who had multiple follicular growth in the presence of an undiagnosed ectopic pregnancy (EP).

DESIGN

Case report.

SETTING

In vitro fertilization unit at a university hospital.

PATIENT(S): A 34-year-old patient with secondary infertility.

INTERVENTION(S): Superovulation with clomiphene citrate (CC) and IUI.

MAIN OUTCOME MEASURE(S): Follicular development with CC stimulation documented by transvaginal ultrasound and beta-hCG levels.

RESULT(S): Two co-dominant follicles were observed with mean diameters of 22 mm and 24 mm. The patient had unexpectedly high levels of beta-hCG at the time of missed menses and was subsequently diagnosed with an ovarian EP.

CONCLUSION(S): Multiple follicular growths can occur in response to CC in spite of the presence of an ovarian EP.
