This is the first recorded case of an immature cervical teratoma arising in one fetus of a twin pregnancy. Although real-time ultrasound detected the presence of an abnormality, its true nature was not established until after histological examination. Extra-amniotic prostaglandin pregnancy termination was performed at 20 weeks' gestation due to the onset of acute hydramnios and the rapid increase in tumor size. Delivery of both fetuses was performed under general anesthesia. Extraction of the abnormal twin was only possible after the tumor was separated off from the fetal neck in utero.
这是首例有记录的双胎妊娠中一个胎儿发生未成熟宫颈畸胎瘤的病例。尽管实时超声检测到存在异常，但直到组织学检查后才确定其真实性质。由于急性羊水过多的出现和肿瘤大小的迅速增加，在妊娠20周时进行了羊膜外前列腺素引产。两个胎儿均在全身麻醉下分娩。只有在子宫内将肿瘤从胎儿颈部分离后，才能取出异常胎儿。
