CTICasesRecurrent Tracheoesophageal Fistula
Imaging findings
Chest CT in a 60-year-old woman with a history of childhood tracheoesophageal fistula (TEF) repair demonstrates a dilated esophagus, a tracheal diverticulum, and a persistent small fistulous tract between the posterior wall of the trachea and the anterior esophagus. Bronchoscopy directly visualized the small fistulous opening with bubbling secretions.
Key takeaways
Tracheoesophageal fistulas repaired in childhood can occasionally recur or manifest as persistent micro-fistulas in adulthood. Patients often present with chronic cough, recurrent aspiration pneumonia, or dysphagia, and the diagnosis can be confirmed via CT, esophagography, or direct bronchoscopic/endoscopic visualization.
