Sirenomelia also known as mermaid syndrome is a partial or complete fusion of lower extremities associated with visceral anomalies. It is a rare anomaly with a poor prognosis. Maternal age less than 20 years, maternal diabetes mellitus, and monozygotic twinning are some of the known risk factors. Diagnosis can be made via antenatal ultrasound or typical physical appearance after birth. A 2200 g baby was born from 18-year-old non-consanguineous mother via assisted breech delivery. The baby had fused lower limbs with 10 toes, absent external genitalia, and a single umbilical artery. It was small for gestational age. The baby was passed away after 30 min of birth. Young maternal age (18 years) was the identified risk factor for sirenomelia in this case. We recommend an early routine ultrasound anomaly scan in all pregnant women particularly for early detection and termination of pregnancy as the prognosis is poor. Avoiding teenager pregnancy and strict control of blood sugar in diabetic mothers can decrease this anomaly.
美人鱼综合征也被称为并腿畸形，是一种下肢部分或完全融合并伴有内脏异常的疾病。它是一种罕见的异常情况，预后较差。母亲年龄小于20岁、母亲患有糖尿病以及单卵双胎是一些已知的风险因素。诊断可以通过产前超声或出生后的典型外貌来进行。一名体重2200克的婴儿由一位18岁非近亲结婚的母亲经臀位助产分娩出生。该婴儿下肢融合，有10个脚趾，外生殖器缺失，且只有一条脐动脉。其出生时孕周小于胎龄。婴儿出生30分钟后死亡。年轻的母亲年龄（18岁）是该病例中美人鱼综合征的确定风险因素。我们建议所有孕妇进行早期常规超声异常扫描，特别是为了早期发现并终止妊娠，因为预后较差。避免青少年怀孕以及严格控制糖尿病母亲的血糖可以减少这种异常情况。
