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. Therefore, maintaining a heightened level of suspicion is crucial for timely diagnosis and effective management of urachal cysts, particularly in emergency room settings. We present the case of a 24-year-old male who exhibited clinical signs consistent with an acute abdomen. The use of imaging techniques confirmed the presence of an infected urachal cyst, which was successfully treated through surgical intervention.
