Abstract Spontaneous rupture of an ovarian artery aneurysm or pseudoaneurysm (OAA) is a rare, life-threatening cause of retroperitoneal hemorrhage. We present a patient with an undiagnosed left ovarian pseudoaneurysm that ruptured two days after an uneventful vaginal delivery. This condition was initially masked by typical puerperal changes and postpartum complications, however, an urgent transcatheter arterial embolization (TAE) led to a successful outcome. This case report and a literature review highlight the need for awareness of ruptured OAA in the differential diagnosis of severe abdominal pain after childbirth, especially in high-parity women, to improve maternal and perinatal outcomes.
