Findings of extrathyroid lesions encountered with thyroid sonography

Abstract

OBJECTIVE: The purpose of this presentation is to illustrate the normal sonographic anatomy of the anterior neck region and the sonographic findings of various kinds of extrathyroid lesions. METHODS: Cases of extrathyroid lesions were collected and reviewed retrospectively from our archives. All of the sonographic examinations were performed with high-frequency (5- to 15-MHz) linear array transducers. RESULTS: The normal sonographic anatomy of the anterior neck region and various pathologic conditions of patients with extrathyroid lesions are discussed. CONCLUSIONS: Sonography is a useful imaging method for evaluating anterior neck anatomy and various pathologic conditions in patients with extrathyroid lesions.
