Spontaneous Ovarian Hyperstimulation Syndrome in a Partial Molar Pregnancy with Early Onset Severe Pre-eclampsia at 15 Weeks Gestation

Abstract

Ovarian hyperstimulation syndrome is a well-known entity in assisted reproductive technology. However, it is unusual for this entity to occur without any medications that stimulate follicle stimulating hormone. Herein, we describe a case where a partial molar pregnancy with high human chorionic gonadotropin promiscuously activated follicle stimulating hormone receptors has resulted in spontaneous ovarian hyperstimulation syndrome. There are only eight other cases documented per our literature search of ovarian hyperstimulation syndrome in molar gestations, and this is the third report in partial molar gestation. In our case, it is an unique development of severe early onset pre-eclampsia in the second trimester. Our goal is to discuss the nuances in management of this entity as well as to add the available body of research on this subject.
