case_images: Endoscopic examination of esophageal cancer. (A) Circumferential esophageal lesions with significant esophageal stenosis. (B) Arrows indicate an irregular or shadowless first hyperechoic layer, with a hypoechoic tumor extending into the fifth hyperechoic layer, without invasion of the aorta.

case_images: Endoscopy revealed an ulcerative lesion located 26 to 35 cm from the incisors (Fig. 1A). The endoscopic ultrasound indicated infiltration into the muscularis propria and adventitia of the esophagus, with the tumor positioned adjacent to the descending aorta; however, no signs of invasion were observed (Fig. 1B).
case_images: CT images of esophageal stent placement. (A) No false aortic aneurysm was detected at the indicated location prior to esophageal stent placement. (B) and (C) show arrows indicating the presence of a new pseudoaortic aneurysm following esophageal stent insertion. CT = computed tomography.

case_images: These findings were confirmed further by computed tomography, which provided additional support for assessing the tumor's localization features (Fig. 2A). The computed tomography angiography subsequently revealed a pseudoaneurysm near the esophageal stent, which suggests the presence of an AEF (Fig. 2B, C).
case_images: Three-dimensional reconstructed computed tomography image of blood vessels. (A) and (B) show the esophageal stent in contact with the aorta. (C) The esophageal stent remained intact and without any fractures.

case_images: The stent remained intact and was snugly positioned against the aorta, with no foreign bodies detected within the aorta (Fig. 3).
