A rare but severe complication of endometriosis during pregnancy is spontaneous hemoperitoneum in pregnancy (SHiP), severe intraabdominal bleeding that can be life threatening.Case Report We present the case of a patient with SHiP at 29 weeks of pregnancy. A supraumbilical midline laparotomy was performed, and pelvic exploration revealed a lacerated and bleeding right ovary. Right annessiectomy was performed, and a cesarean section was performed because hemostasis was not achievable. A healthy baby was born, and hemostasis was finally achieved.Conclusion We believe that in gravid females with a history of endometriosis, severe abdominal pain, and a reduction of hemoglobin, physicians should always suspect SHiP. Because SHiP is a life-threatening condition for both the mother and the baby, a prompt diagnosis must lead to prompt treatment.
