Ovarian hyperstimulation syndrome in a spontaneous pregnancy with a complete hydatidiform mole.

Objective: To present a case of ovarian hyperstimulation syndrome occurring after evacuation of a spontaneously conceived hydatidiform molar pregnancy.

Design: Case report.

Setting: University-affiliated teaching hospital.

Patient(s): A 19-year-old nulliparous woman who underwent vacuum curettage for a complete hydatidiform molar pregnancy was admitted to our hospital with ovarian hyperstimulation syndrome and large bilateral pleural effusions.

Intervention(s): Intravenous fluid, deep vein thrombosis prophylaxis, placement of bilateral chest tubes.

Main Outcome Measure(s): Management of ovarian hyperstimulation syndrome.

Result(s): Ultrasonography and computed tomography showed large multicystic ovaries, marked ascites, and large pleural effusions that required placement of bilateral chest tubes. She had recovered by hospital day 14.

Conclusion(s): Ovarian hyperstimulation syndrome may develop in women who have undergone treatment for a hydatidiform mole, and serious complications may develop rapidly.
