We describe a case of concordant body stalk anomaly in monozygotic twins that manifested with umbilical cord agenesis, evisceration of abdominal contents, and multiple gastrointestinal, genitourinary, and skeletal anomalies. Body stalk anomaly in twin gestation is extremely rare and poses an embryological interest. We suggest that the hypothesis of 'incomplete twinning' might contribute to the pathogenesis of this syndrome complex.
我们描述了一例单卵双胞胎中一致的体蒂异常病例，表现为脐缺如、腹腔脏器外翻以及多种胃肠道、泌尿生殖系统和骨骼异常。双胎妊娠中的体蒂异常极为罕见，具有胚胎学研究价值。我们认为“不完全孪生”假说可能有助于解释这一综合征的发病机制。
