Iatrogenic esophageal perforation with esophageal-pleural fistula-CT esophagography
Distal esophageal stricture, subjected to endoscopic dilatation followed by severe chest pain and dyspnea for two days

CT study shows the following:
- mural thickening of the distal esophagus with contrast leak within the pleural spaces bilaterally indicating iatrogenic esophageal perforation with esophageal-pleural fistula
- bilateral chest tubes with residual (hydro/pyo-pneumothorax) associated with compression atelectasis of the lung bases.
- moderate dilatation of the esophagus matching with the patient’s known history of distal stricture
- the contrast is seen reaching the stomach and opacifying its lumen
In this case, fluoroscopy was not available, so we used CT esophagography instead with very good diagnostic results
CT esophagography is a CT study designed to primarily evaluate the esophagus, particularly in the situation of esophageal trauma and potential perforation. It has been developed partly as an alternative to fluoroscopic barium swallow evaluation in this situation.
As the patient general condition was bad, he was unable to drink the oral contrast so a nasogastric tube was placed with an injection of the diluted water-soluble oral contrast through
