Submucosal esophageal abscess evolving into intramural submucosal dissection: A case report

Figure 2 Computed tomography showed a double-barreled esophagus without thickening of the esophageal wall. A: Chest computed tomography scan showed eccentric thickening of the esophageal wall; B: Chest computed tomography scan taken immediately after endoscopy showed worsened diffuse thickening of the esophageal wall; C: Chest computed tomography scan taken 2 mo after endoscopy showed that the thickening of the esophageal wall was alleviated with a double-barreled esophagus visible.
