    If the urachus fails to close during fetal life, it can result in anatomical abnormalities such as a urachal cyst, urachal fistula, urachal diverticulum or urachal sinus. In very rare cases the urachus can fail to close fully. This can lead to a condition known as a patent urachus (also urachal fistula). Although it is mainly immediately ...

    A urachal cyst is a sinus remaining from the allantois during embryogenesis. It is a cyst which occurs in the remnants between the umbilicus and bladder. [1] This is a type of cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterized by abdominal pain, and fever if ...
