Spontaneous ovarian hyperstimulation syndrome (s-OHSS) is a rare finding that occurs in early pregnancy. There is a rapidly increasing ovarian size secreting vasoactive substances that lead to fluid shift into third spaces. This occurs in the absence of exogenous hormonal therapy. We present two cases of s-OHSS. A 35-year-old gravida 4 para 3 presented with complaints of progressive abdominal pain, distension, nausea, vomiting, and difficulty in breathing at 10 weeks gestation. On imaging, a singleton intrauterine gestation, enlarged ovaries containing multiple cysts, and moderate ascites were seen. Second, a 17-year-old primigravida presented with abdominal distension and pain and bleeding per vaginam following 4 months amenorrhea. A bulky uterus containing a large hyperechoic structure with multiple cystic spaces in keeping complete molar gestation and enlarged ovaries containing multiple cysts were seen on ultrasound imaging. The singleton gestation was managed successfully to term with conservative therapy tailored to clinical symptoms.
