Infected urachal remnant presenting with purulent umbilical discharge in an adult: A diagnostic and surgical challenge

Urachal anomalies are rare in adults and may mimic common abdominal conditions, leading to delayed or missed diagnosis. We report a 47-year-old man presenting with isolated purulent umbilical discharge initially mistaken for a superficial abscess. Contrast-enhanced computed tomography revealed a rim-enhancing lesion with a non-communicating urachal tract. The patient underwent successful laparoscopic excision, and histopathology confirmed an infected urachal remnant without malignancy. Recovery was uneventful, with no recurrence at one month. This case emphasizes the diagnostic value of early imaging and supports laparoscopic urachectomy as a safe, definitive management for infected adult urachal remnants.
