Background: Spontaneous ovarian hyperstimulation syndrome rarely occurs during pregnancy and is usually associated with high levels of human chorionic gonadotropin, in conditions such as molar or multifetal pregnancies. Case report: Here we report spontaneous ovarian hyperstimulation in a patient presenting with missed abortion at 16th week of gestation, when serum B-subunit human chorionic gonadotropin level detected to be 400 milliunit per milliliter. Evacuation and curettage was performed and the ovaries returned to about normal size two months later. Conclusion: Spontaneous ovarian hyperstimulation syndrome can develop even in the presence of very low levels of hCG in missed abortion.
