A 35-year-old woman with a history of myomectomy underwent in vitro fertilization and became pregnant. Transvaginal ultrasound revealed a gestational sac within the subserosal area of the posterior uterine wall. The patient was treated successfully with conservative surgery, and the pathologic evaluation of the excised mass demonstrated chorionic villi involving myometrium. Early in a subsequent pregnancy, placental invasion through the sinus tract was detected. However, the pregnancy outcome was uneventful. This constitutes the first report of subserosal implantation in the uterine body. Our findings suggest that the probable pathogenesis of this rare variant of intramural pregnancy is implantation through a sinus tract made during a previous uterine surgery.
一名有子宫肌瘤切除术史的35岁女性接受了体外受精并怀孕。经阴道超声检查发现子宫后壁浆膜下区域有一个妊娠囊。患者通过保守手术成功治疗，切除肿块的病理评估显示绒毛膜绒毛累及子宫肌层。在随后的一次妊娠早期，检测到胎盘通过窦道侵入。然而，妊娠结局顺利。这是子宫体浆膜下植入的首例报告。我们的研究结果表明，这种罕见的壁内妊娠变体的可能发病机制是通过先前子宫手术形成的窦道植入。
