Fig. 8 79-year-old man with stent placed for palliation of
tracheoesophageal fistula caused by squamous cell carcinoma of esophagus. Left
posterior oblique spot image from single-contrast esophagram shows irregular
luminal narrowing (white arrows) in distal end of stent. Also note
barium in left mainstem bronchus (black arrows) from
esophagobronchial fistula that presumably developed as a result of tumor
ingrowth through adjacent uncovered distal portion of stent.
