Killian-Jamieson Diverticula Mimicking Thyroid Nodule on Ultrasound: Radiographic Findings in Two Patients

ABSTRACT

Killian-Jamieson diverticula are lateral diverticula in the cervical esophagus. Because of their location, they have been found incidentally during ultrasound (US) and they've sometimes been mistakenly identified for thyroid nodules. We describe here the US findings, the fine needle aspiration (FNA) procedure and the esophagography of a Killian-Jamieson diverticulum in a 70-year-old man. This diverticulum was considered to be a calcified thyroid nodule until we performed FNA. We will discuss the sonographic findings that are helpful for differentiating Killian-Jamieson diverticula from thyroid nodules. In addition, we describe the US findings of a small Killian-Jamieson diverticulum in a 34-year-old woman.
