title: Infected urachal remnants in the adult: case report and review.
abstract: Abnormalities of the urachus in adults are uncommon. Urachal tract remnants that abnormally remain patent are subject to infection. Urachal infection is frequently confused with a wide spectrum of midline intraabdominal or pelvic inflammatory disorders. Because the literature on urachal infection is primarily limited to articles in urology and surgical specialty journals, many physicians may not be familiar with the varied clinical manifestations. We describe a case of infection of a patent urachus in an adult and review the embryology and anatomy of the urachus as it relates to clinical presentation, evaluation, and management. Infection of a urachal remnant should be included in the broad differential diagnosis of omphalitis and midline abdominal or pelvic infections. Rarely, it may be a cause of recurrent urinary tract infection. Definitive management consists of surgical excision after the institution of antimicrobial therapy.
