Imaging revealed a large\u2010volume hemoperitoneum without identifiable intrauterine or adnexal gestation. Emergency diagnostic laparoscopy demonstrated approximately 5\u2009L of hemoperitoneum and active bleeding from the right uterosacral ligament. The bleeding lesion was excised, and histopathology confirmed ectopic gestation. The patient recovered uneventfully and was discharged on postoperative Day 6.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Uterosacral ligament ectopic pregnancy is an extremely rare but potentially fatal condition.
