Coexistant Meckel's diverticulum and patent urachus: a case report.

Introduction and Clinical Importance: Concurrent remnants of the omphalomesenteric duct and urachus are exceptionally found. Diagnosis of Meckel's diverticulum is mainly incidental, but a patent urachus is usually clinically possible. Case Presentation: We admitted a 48-hour-old female patient for an eviscerated Meckel's diverticulum with a history of urine smelling around the umbilicus. Preoperative ultrasound did not identify an associated urachal anomaly. During emergency surgical exploration, a patent urachus was identified. Both remnants were resected, with the Meckel's diverticulum presenting gastric heterotopia. The postoperative course was unremarkable after a 2-year follow-up. Clinical discussion: An asymptomatic Meckel's diverticulum is usually an incidental finding. In this patient, umbilical cord rupture due to a patent urachus eased the diagnosis. As ultrasound is operator dependent, its negation for associated urachal remnant must still indicate meticulous intraoperative exploration to definitively rule out concurrent urachal remnant when its association with an omphalomesenteric duct remnant is suspected. Conclusion: Association between Meckel's diverticulum and patent urachus is rare, but possible. Identification of both anomalies is crucial for comprehensive management.
