Umbilical cord cysts are rare and the reported associations with abnormal foetal outcomes present challenges in antenatal diagnosis and management.
We report a case of a large umbilical cord cyst detected in the second trimester, with no communication to the foetal bladder. Third trimester review demonstrated oedematous change in the umbilical cord and significantly reduced umbilical artery flow necessitating delivery by emergency caesarean section. Postnatally, the infant was found to have a patent urachus.
This case underlines the importance of antenatal ultrasound surveillance in pregnancies complicated by umbilical cord cysts, limitations in definitive diagnosis and features of cord compression that have not been previously reported.
脐带囊肿罕见，且所报道的与胎儿异常结局的关联给产前诊断和管理带来了挑战。
我们报告一例在孕中期检测到的大型脐带囊肿病例，该囊肿与胎儿膀胱无连通。孕晚期复查显示脐带出现水肿变化，脐动脉血流显著减少，因此需要紧急剖宫产分娩。出生后，发现婴儿存在脐尿管未闭。
该病例强调了在合并脐带囊肿的妊娠中进行产前超声监测的重要性、明确诊断的局限性以及此前未报道过的脐带受压特征。
