Infected Urachal Sinus in an Adult

Hanae Ramdani et al. Cureus. .

Abstract

Urachal anomalies are infrequent in the adult population and may represent a diagnostic challenge. Few cases of urachal sinuses are reported and are usually asymptomatic unless a complication occurs, most likely infectious. Infected urachal sinus' clinical manifestations are a purulent umbilical discharge, abdominal pain, and a periumbilical mass. We report the case of a late presentation of an infected urachal sinus in a male adult. Clinical and imaging features allowed accurate diagnosis. Antibiotic therapy was followed by the urachal remnant's surgical excision. The postoperative course was uneventful. Histological examination revealed no signs of malignancy.

Keywords: abdominopelvic computed tomography; congenital anomaly; infected urachal sinus; urachal sinus; urachus.
