Killian-Jamieson diverticulum: real-time sonographic findings.

Killian-Jamieson diverticulum (KJD) is a pharyngoesophageal diverticulum that can be observed during a neck ultrasound examination. Because of its position, it is frequently misinterpreted as a thyroid nodule. We present a case of an incidental finding of KJD, where changes in shape during dynamic scanning led to the correct diagnosis, preventing from invasive procedures such as fine needle aspiration.
