Upper gastrointestinal bleeding, aneurismatic dilatation of the thoracic aorta and filling defect on the esophagogram: a diagnostic triad suggesting aortoesophageal fistula.
A patient is described with an aneurysm of the thoracic aorta, which has ruptured into the esophagus. An esophageal X-ray contrast study has revealed a filling defect at the contact site of the esophagus and the aortic aneurysm. The filling defect was due to a clot protruding from the aorta into the esophagus. This unique case calls attention to a diagnostic triad: upper gastrointestinal bleeding, aneurysm of the thoracic aorta, and filling defect in the esophagus at its site of contact with the enlarged aorta. This triad suggested aortoesophageal fistula (AEF) in the patient and could help in the diagnosis of atypical cases of AEF, where thoracic aortography has not been performed initially.
