Intramural esophageal dissection(IED) is a rare disorder characterized by a separation of the mucosa and/or submucosa from deeper muscular layers of the esophagus, with or without perforation. Iatrogenic instrumentation such as endoscopy is one of the major causes of IED. We report a case of IED after endoscopy in a patient with hypopharyngeal cancer treated with concurrent chemoradiotherapy, and suggest that a history of chemoradiotherapy can be a risk factor of IED on endoscopy. In this case, chest computed tomography scans show not only typical esophageal double lumen but also eccentric esophageal wall thickening and abnormally thin the other side esophageal wall, and this CT finding may also be important to diagnose IED.
