Killian-Jamieson diverticulum

Killian-Jamieson diverticula are esophageal diverticula. Like the more common Zenker diverticulum, it is a false diverticulum and represents an outpouching of mucosa through a muscular defect (in this case the Killian-Jamieson space 2). 


They are located just below the cricopharyngeal muscle, anteriorly and laterally, as a left-sided or less commonly bilateral outpouchings from the cervical esophagus. It is infrequently encountered compared with Zenker diverticulum. Not only are they smaller than Zenker diverticulum (usually <1.5 cm), but they also are rarely symptomatic. 

Practical points

It is evaluated when a thyroid nodule is encountered near the esophagus, particularly if it changes its shape during an ultrasound on swallowing maneuver 3.
