Congenital tracheoesophageal fistula successfully diagnosed by CT esophagography

Figure 1 Esophagoscopy reveals a depressed lesion (arrows) that looked as if it was punched at a distance of 23 cm from the incisors in the middle intrathoracic esophagus (E).

Figure 2 A: CT esophagography demonstrates communication between the middle intrathoracic esophagus and the distal trachea just proximal to the carina (arrows). Note a distortion caused by tube inserted into the esophagus (arrowheads). T, trachea; E, esophagus. B: Virtual esophagoscopy shows the orifice of the fistula (arrows) and it is similar to that of (conventional) esophagoscopy (Figure 1). NT, naso-gastric tube; E, esophagus. C: Virtual bronchoscopy also demonstrates the orifice of the fistula (arrows). T, trachea.

Figure 3 Pathological examination of the resected specimen revealed that the fistula was lined by benign squamous epithelium with the muscularis mucosa (arrowheads).
