Case of ovarian hyperstimulation syndrome (OHSS) in pregnancy is rare. The complications include ascites, thromboembolism, pulmonary and hemodynamic/renal disorders, abortion, intrauterine fetal demise and preterm delivery. In this case, we found OHSS in spontaneous pregnancy with maternal mirror syndrome as complication of sacrococcygeal teratoma that increased maternal morbidity and mortality rate.
