A rare case of infected urachal cyst leading to intestinal obstruction in a 3-month-old boy with febrile urinary tract infection: Case report.

RATIONALE

Urachal anomalies are rare and can present with various clinical manifestations. Urachal remnants, in particular, can be difficult to diagnose because of atypical symptoms at presentation. This study reports a case of intestinal obstruction in an infant secondary to an infected urachal cyst.

PATIENTS CONCERNS

A 3-month-old boy with a known febrile urinary tract infection developed acute abdominal distension.

DIAGNOSES

Abdominal ultrasound (US) and computed tomography (CT) revealed a nonspecific, ill-defined soft tissue density at the mid-abdomen, associated with intestinal obstruction.

INTERVENTIONS

Emergency exploratory laparotomy was performed. The site of the obstruction was found to be at the mid-small bowel; the proximal small bowel was markedly distended, and the small bowel and sigmoid colon were adherent to urachal remnant. The urachal remnant was excised, and the peritoneal adhesions were lysed.

OUTCOMES

The day after surgery, the patient was discharged without any complications.

LESSONS

Intestinal obstruction is an exceedingly rare presentation of urachal remnants. This case highlights that urachal anomalies should be considered in the differential diagnosis in patients with intestinal obstruction and a concurrent febrile urinary tract infection.
