Abstract

Lye ingestion is a rare cause of an aortoesophageal fistula (AEF). We report a case of a 75-year-old woman with an AEF due to lye ingestion. Since an endoscopy cannot be engaged into the esophagus due to orifice stricture, we adopted computed tomography (CT) as a diagnostic tool. An AEF was confirmed by surgery.

  Fig. 1 An aortoesophageal fistula due to lye ingestion in a 75-year-old woman. A. Unenhanced axial CT image shows high attenuation in the esophageal lumen due to hemorrhage (open arrow). B. Contrast-enhanced axial CT image shows a contrast-filled small outpouching sac (arrow) from the thoracic aorta connecting into the esophageal lumen at the level of ninth thoracic vertebral body. C, D. 3-D reconstruction images using a volume rendering technique shows an small outpouching sac (arrow) from the aorta, which protruded into the esophagus.
