[Infected urachal cyst].

The urachus is a vestigial remnant of the cloaca and allantois. It is usually obliterated at early postnatal life. When this obliteration is incomplete, in addition to congenital urachal anomalies such as patent urachus, umblical-urachal sinus, vesico-urachal diverticulum, and urachal cyst, acquired urachal pathologies as infections and neoplasms can emerge. In this case report we will evaluate an infected urachal cyst established in a 26 year-old female. She presented with complaints of abdominal pain and umblical discharge. suprapubic sensitivity, abdominal mass with an overlying hyperemic skin were detected. Patient whose clinical manifestations suggested the diagnosis of infected urachal cyst which was also supported by USG and CT findings was operated. Total cyst excision was performed.
