Figure 2 Findings at upper endoscopy and chest computed tomography scan (CT scan) (case 2). A: Upper endoscopy revealing a stenotic ulcerative tumor in the proximal esophagus, 22-29 cm from incisors. Histological examination of esophageal biopsies confirmed the diagnosis esophageal squamous cell carcinoma. B: Chest CT scan showing a tumor mass in the proximal esophagus with suspected tumor invasion in the trachea.

Figure 4 Initial findings at positron emission tomography-computed tomography scan (PET-CT scan) (case 4). A: Chest CT scan image with a circumferential wall thickening of the thoracic colonic interposition over a length of 10 cm, not clearly separated from the thyroid and left brachiocephalic vein. Locoregional suspected lymph nodes (< 1 cm). B: PET-CT scan showing a PET-positive lesion in the thoracic colonic interposition. No PET-positive lesions or lymph nodes.
