An Infected Urachal Cyst With Umbilical Granuloma in an Adult Patient.

The urachus, an embryonic organ associated with the bladder, typically undergoes degeneration shortly after birth. Inadequate closure of the urachus can result in urachal malformations, with the most common being a urachal cyst. Failure to promptly identify and address this condition can lead to complications such as sepsis, fistula development, and cyst rupture, mimicking symptoms of peritonitis.
