Ruptured Corpus Luteum with Hemoperitoneum in Early Pregnancy.

We present a 24-year-old woman with a positive β-human chorionic gonadotropin at 5 weeks and 4 days with acute postcoital lower abdominal pain. Imaging revealed acute intra-abdominal bleeding and no intrauterine or extrauterine fetal sac present. We considered both ruptured ectopic pregnancy and ovarian hemorrhage—recognizing that differentiation is difficult. At emergency laparoscopy (Fig. 1), the enlarged left ovary was actively bleeding, and luteal rupture with hemorrhage was diagnosed. Intraperitoneal lavage was performed, and hemostasis was achieved using bipolar coagulation and hemostatic agents (SURGICEL Powder Absorbable Hemostat; Ethicon Endo-Surgery, Cincinnati, OH).
