Esophago-pleural fistula associated with thoracic aortic aneurysm is a rare and lethal complication. We report the case of a 62-year-old male who suffered from esophago-pleural fistula 56 days after thoracoabdominal aortic surgery. Contrasted CT showed that the fistula occurred at the level of the esophagus compressed by rapid dilatation of thoracic aorta and endoscopy revealed no ischemic signs on esophageal mucosa, demonstrating that the cause of esophago-pleural fistula was compression necrosis due to rapid dilatation of the thoracoabdominal aortic aneurysm.
