ABSTRACT
A Killian-Jamieson diverticulum is a type of pharyngoesophageal diverticuli and can be visualized on thyroid ultrasonography (US). Although most of the lesions are located in the deep layer of the left thyroid lobe, we encountered a case of a right-sided Killian-Jamieson diverticulum in a 64-year-old man that was mistaken for a thyroid nodule on US. We describe the US, computed tomographic, and esophagraphic findings of this case. In addition, we describe the US findings of a left Killian-Jamieson diverticulum in a 55-year-old woman that was seen as a hyperechoic mass in the thyroid on US.. The shape and echogenecity of the diverticulum changed with swallowing as depicted on real-time US and the need for a needle aspiration biopsy was avoided.
