Osseous metaplasia of the endometrium is a rare disorder and can be associated with infertility. Although successful diagnosis and treatment have been widely reported, correct diagnosis in many cases still represents a challenge.
A 40-year-old woman complaining of infertility presented with a diagnosis of retained intrauterine device (IUD) on ultrasound. Hysteroscopy revealed a normal endometrial cavity, but no IUD was visualized. Curettage pathology specimens showed chronic endometritis and calcification. Repeat hysteroscopy was performed because of persistent echogenic foci in the endometrium on follow-up ultrasound. Several irregular and calcified plaques were successfully removed.
Osseous metaplasia can be misdiagnosed because of its rare incidence. Physicians should be aware of osseous metaplasia in the differential diagnosis of patients with uncertain history who present with a sonographic image resembling an IUD.
子宫内膜骨化生是一种罕见的病症，可能与不孕有关。尽管已有关于成功诊断和治疗的广泛报道，但在许多病例中正确诊断仍然是一项挑战。
一名40岁主诉不孕的女性，超声检查诊断为宫内节育器（IUD）残留。宫腔镜检查显示子宫内膜腔正常，但未发现IUD。刮宫病理标本显示慢性子宫内膜炎和钙化。由于随访超声检查发现子宫内膜持续存在强回声灶，故再次进行宫腔镜检查。成功切除了几块不规则的钙化斑。
骨化生因其发病率低可能会被误诊。对于病史不明且超声图像类似IUD的患者进行鉴别诊断时，医生应考虑到骨化生。
