Endoscopic and imaging studies. (A) Endoscopic examination revealed two lamellar mucosal lesions in the upper esophagus, located at 11 o'clock and 4 o'clock, respectively (arrows). The mucosal lesion at 4 o'clock was larger and deeper, with dark blood on the surface. (B) Contrast enhanced computed tomography scan showed a patchy enhanced shadow extending from the right cervical root to the right common carotid artery (arrow), with surrounding free air bubbles. The shadow was close to the esophageal entrance. (C) Ultrasonography examination revealed a 33 x 27 mm cystic common carotid artery pseudoaneurysm with partial thrombosis (arrow). (D) Postoperative histopathology report of resected fistula tissue showed infiltration of inflammatory cells (arrow).

The mucosal lesion at 4 o'clock was larger and deeper, with dark red blood on the surface (Figure 1A). The shadow was close to the esophageal entrance (Figure 1B). Ultrasonography examination revealed a 33 x 27 mm cystic CCA pseudoaneurysm with partial thrombosis (Figure 1C). The histopathology report of resected fistula tissue showed infiltration of inflammatory cells (Figure 1D).
