The Diagnostic Challenge of an Accompanying Tracheal Bronchus and Meckel's Diverticulum: A Case Report

Background: A tracheal bronchus is a rare congenital abnormality in which an abnormal bronchus arises from the trachea. The prevalence of a tracheal bronchus is approximately ۰.۹% to ۳% in the population. Due to its low prevalence, association with other anomalies, and overlapping symptoms, this condition often goes undiagnosed or is diagnosed late. Case Report: This article discusses a case of an infant born at ۳۷ weeks’ gestation. The baby required a right thoracotomy after experiencing cyanosis during feeding, leading to a diagnosis of tracheoesophageal fistula. During bronchoscopy, an abnormal orifice was noted above the carina. Subsequently, contrast material was introduced into the orifice and evaluated under fluoroscopy. Conclusion: The fluoroscopic examination confirmed that the observed orifice did not represent a tracheoesophageal fistula (TEF). Fluoroscopy findings showed that the orifice was an accessory bronchus connected to the right lung. In this case, the use of Visipaque during fluoroscopy significantly aided the diagnosis. The routine use of contrast agents for diagnosing tracheobronchial diseases in children is uncommon. The significant aspect of this case is the utilization of contrast material during fluoroscopy, which facilitated an accurate diagnosis. The low incidence of tracheal bronchus has resulted in limited progress in diagnostic and treatment research. When tracheobronchial anomalies are suspected, the use of contrast agents during imaging can expedite diagnosis.
