Omphalitis associated with uracus malformation in a neonate: a case report

Abstract

Introduction: the involution of the urachus gives rise to the middle umbilical ligament; When there are failures during the obliteration process, anomalies such as the urachal cyst may occur with important clinical repercussions. Case: A 28-day-old neonate was brought in due to pus leaking from the navel and fever, associated with abdominal wall cellulitis. Omphalitis and infraumbilical foreign body were initially suspected after the first ultrasound, but due to persistence of symptoms and a second ultrasound, the diagnostic impression changed to a persistent urachus cyst. After voiding cystourethrography, no fistulous tract was observed towards the umbilicus, leading to the diagnosis of urachal sinus and referral to pediatric surgery through outpatient consultation. Discussion: Urachal malformations are rare pathologies whose presence may be evident at birth through anomalies of the umbilical cord or later in adolescence and adulthood due to recurrent urinary or umbilical infections. The diagnosis is imaging, and the definitive management is surgical; complications are rare. Conclusion: In a newborn or infant with a wet navel, we must rule out a congenital malformation of the persistent urachus type and whose first diagnostic method is ultrasound, complement it with studies of the urinary tract and provide definitive treatment through excision of the malformation, in If there is an infection, it is deferred until it is resolved.
