Abstract：
Endometrial osseous metaplasia (EOM) is a rare condition characterized by abnormal bone formation in the endometrium. This acts as a foreign body in the uterus. The commonest clinical presentation is secondary infertility. Transvaginal ultrasonography is the mainstay of first-line diagnosis. Hysteroscopy confirms the diagnosis and aids in complete removal. Diagnosis of this condition is crucial as post-treatment fertility outcomes are good. This case highlights the importance of three-dimensional ultrasonography before infertility treatment and after hysteroscopic removal of osseous metaplasia to look for reactive endometrial polyps which may interfere with the embryo implantation and spontaneous conception altering the post-surgical fertility outcome.
摘要：
子宫内膜骨化生（EOM）是一种罕见的疾病，其特征是子宫内膜骨形成异常。这在子宫中起异物的作用。最常见的临床表现是继发性不孕症。经阴道超声检查是一线诊断的主要手段。宫腔镜检查可确认诊断并有助于完全切除。这种情况的诊断至关重要，因为治疗后的生育结果良好。该病例强调了在不孕症治疗之前和宫腔镜下切除骨化生后进行三维超声检查的重要性，以寻找可能干扰胚胎植入和自发受孕改变手术后生育结果的反应性子宫内膜息肉。
