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

## TL;DR

A 47-year-old man with a rare infected urachal remnant was successfully treated with laparoscopic surgery after initial misdiagnosis.

## Contribution

This case highlights the importance of early imaging and laparoscopic urachectomy for diagnosing and treating infected adult urachal remnants.

## Key findings

- Contrast-enhanced CT identified a non-communicating urachal tract in a patient with purulent umbilical discharge.
- Laparoscopic excision led to full recovery with no recurrence after one month.
- Histopathology confirmed an infected urachal remnant without malignancy.

## Abstract

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.
