Truncal duplication represents one of the rare forms of conjoined twins. We observed a male infant with a truncal duplication; in the host twin no pathology was found except an atrial septal defect and a large omphalocele. The parasitic twin was attached to the xiphoid region (xiphopagus) in an opposite and "horseriding" manner, was acephalic, and had multiple gastrointestinal, genitourinary, and skeletal anomalies. The junction site consisted of lipoid and muscular structures. Surgical separation was done without any difficulty. The abdominal defect was repaired primarily. The host twin is doing well.
躯干重复畸形是联体双胎中罕见的一种形式。我们观察到一名患有躯干重复畸形的男婴；在主胎中，除了房间隔缺损和巨大脐膨出外未发现其他病变。寄生胎以相反且“骑跨”的方式附着于剑突区域（剑突联胎），无头，并有多处胃肠道、泌尿生殖系统和骨骼异常。连接部位由类脂和肌肉结构组成。手术分离顺利完成。主要修复了腹部缺损。主胎情况良好。
