Killian-Jamieson Diverticulum Mimicking a Suspicious Thyroid Nodule: Sonographic Diagnosis

Abstract

Killian-Jamieson diverticulum is a rare form of pharyngoesophageal diverticula emerging in the anterolateral wall of the cervical esophagus. We present a case of Killian-Jamieson diverticulum that mimicked a thyroid nodule on sonography (US), and for which a US-guided fine-needle aspiration (FNA) was performed. The possibility of Killian-Jamieson diverticulum should be considered when a thyroid nodule is seen adjacent to the esophagus even without US change during/after swallowing.
