Killian-Jamieson diverticulum
Updates to Article Attributes
Killian-Jamieson diverticula are oesophageal 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 oesophagus. 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.
Radiographic features
On pharyngoesophagography, it usually appears as a left-sided outpouching from the proximal cervical esophagus below the cricopharyngeus. Less frequently, the outpouchings may be bilateral (25%) 4.
Practical points
It is evaluated when a thyroid nodule is encountered near the oesophagus, particularly if it changes its shape during an ultrasound on swallowing manoeuvre 3.
