Abstract
A 53-year-old man was admitted because of progressive dysphagia and retrosternal pain for 20 days. Esophagogastroduodenoscopy showed an irregular submucosal bulge on the distal esophageal wall. A barium swallow showed a triangular-shaped outpouching of contrast material with minimal contained extravasation into the periesophageal area. Enhanced CT showed thickening of the distal esophagus with an area containing air and septa. FDG PET/CT showed intense FDG uptake of the thickened esophageal wall mimicking malignancy. Endoscopic ultrasonography-guided biopsy of the submucosal mass revealed granulation tissue. The imaging and pathologic findings were consistent with chronic esophageal perforation with periesophageal abscess.
