The following report describes the case of an ectopic pregnancy with contralateral corpus luteum after spontaneous conception. The patient was a 33- year-old female (gravida 3, segmentary C sections 3), with positive pregnancy test, and an Intrauterine Device (IUD). The patient was asymptomatic. At vaginal ultrasound, we observed an anteverted uterus of normal shape and size, a 20 x 12 mm intramural myoma and an irregular endometrial thickness of 16.5 mm, with no intrauterine sac. An ectopic pregnancy in the left Fallopian tube and a contralateral corpus luteum were detected, possibly as consequence of ovum pick up through the opposite tube (oocyte transmigration). Further laparoscopic and histopathologic studies confirmed our findings, and the ectopic pregnancy was successfully removed. In conclusion, oocyte transmigration is a common event and should be account when we wish to provide medical advice to patients with a single Fallopian tube trying to conceive. There are real chances for a patient to become pregnant even when only a single tube is present.
以下报告描述了一例自然受孕后宫外孕伴对侧黄体的病例。患者为 33 岁女性（孕 3 产 3，剖宫产 3 次），妊娠试验阳性，宫内节育器（IUD）在位。患者无症状。经阴道超声检查，我们观察到子宫前位，大小正常，有一个 20 x 12 毫米的宫壁肌瘤和不规则的 16.5 毫米厚的子宫内膜，未见宫内孕囊。左侧输卵管宫外孕和对侧黄体被发现，可能是由于对侧输卵管取卵（卵母细胞迁移）所致。进一步的腹腔镜和组织病理学研究证实了我们的发现，并成功切除了宫外孕。总之，卵母细胞迁移是一种常见现象，当我们希望为试图怀孕的单侧输卵管患者提供医疗建议时，应该考虑到这一点。即使只有单侧输卵管，患者仍有真正怀孕的机会。
