Popis: Abstract Background Killian–Jamieson diverticulum, which is a relatively rare pharyngoesophageal diverticulum, is difficult to distinguish from Zenker’s diverticulum. Because major points of the relevant surgical procedures for these two entities differ, it is important to make an accurate diagnosis. We herein report a case of Killian–Jamieson diverticulum initially diagnosed as Zenker’s diverticulum. Case presentation A 56-year-old man complaining of discomfort during swallowing was diagnosed with pharyngoesophageal diverticulum. He was initially diagnosed with Zenker’s diverticulum before surgery, but the diverticulum actually arose from the left side of the esophageal wall, at the level of the cricoid cartilage and below the cricopharyngeal muscle. We therefore ultimately diagnosed this case as Killian–Jamieson diverticulum during surgery, and were able to preserve the muscle above the diverticulum, which would normally have to be cut when treating a case of Zenker’s diverticulum. Conclusion To make an accurate diagnosis, clinical and surgical findings are important to consider, including the location of the diverticulum and the relationship between the diverticula and cricopharyngeal muscles or between the diverticula, thyroid cartilage and cricoid cartilage.
