Ectopic pregnancy (EP) constitutes 1%-2% of all pregnancies and is one of the leading causes of maternal morbidity and mortality. The most common site of ectopic pregnancy is the ampulla. Ectopic ovarian pregnancy (EOP) is one of the rare events, with an incidence of 0.5%-3% of all pregnancies. The incidence is higher in intrauterine device users or assisted reproductive techniques. The precise aetiology and pathogenesis of EOP remain elusive. Clinically, EOP mirrors the presentation of tubal pregnancy or a ruptured luteal cyst, often leading to life-threatening hypovolemic shock. Transvaginal sonography is the primary diagnostic tool. Still pinpointing the exact location early on poses challenges, and it's usually misinterpreted as a tubo-ovarian mass, hemorrhagic cyst, or luteal cyst. Furthermore, while a suboptimal rise in serum beta-human chorionic gonadotropin (β-hCG) levels may indicate pregnancy, it doesn't definitively confirm EOP. Only histopathological examination offers a conclusive diagnosis. This paper discusses an EOP case in a young woman who experienced five months of amenorrhea and exhibited no traditional risk factors, underscoring the significant challenges inherent in preoperative diagnosis.
异位妊娠（EP）占所有妊娠的1%-2%，是孕产妇发病和死亡的主要原因之一。异位妊娠最常见的部位是输卵管壶腹部。卵巢异位妊娠（EOP）是一种罕见情况，占所有妊娠的0.5%-3%。在宫内节育器使用者或辅助生殖技术中，其发生率更高。EOP的确切病因和发病机制仍不清楚。临床上，EOP的表现类似于输卵管妊娠或黄体囊肿破裂，常导致危及生命的低血容量性休克。经阴道超声检查是主要的诊断工具。然而，早期准确确定确切位置仍具有挑战性，它通常被误诊为输卵管卵巢肿块、出血性囊肿或黄体囊肿。此外，虽然血清β-人绒毛膜促性腺激素（β-hCG）水平升高不理想可能提示妊娠，但并不能明确确诊EOP。只有组织病理学检查才能提供确诊。本文讨论了一名年轻女性的EOP病例，该女性闭经五个月且无传统危险因素，强调了术前诊断所面临的重大挑战。
