Giant Bladder Diverticulum in A Female Infant Mimicking Intraperitoneal Mass.

Urinary bladder diverticula can be either primary (congenital) or secondary (acquired) and are more commonly observed in males, sometimes in association with syndromes. The condition presents with a wide range of symptoms, while some cases may remain asymptomatic. Management options include conservative treatment, endoscopic intervention, or surgery, depending on patient factors, clinician expertise, and available resources. In this case report, we present a 5-month-old female infant with progressive abdominal distension and reduced urine output. She was managed surgically and recovered well postoperatively. This case underscores the diverse presentation of surgical pathologies in children, emphasizing the need for individualized management strategies, the use of advanced radiological investigations to confirm diagnosis, and a multidisciplinary approach in a tertiary care setting.
