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).
Pathology
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.
