[Sonography of the neck-aspects of differential diagnosis].

Abstract

Sonography is the preferred method for primary diagnosis and acute treatment of pathologies involving the neck's soft tissues. Technological advances, particularly high image resolution and multiparametric ultrasound, have improved diagnostic performance. Clinical interest focuses on examining the cervical lymph nodes, salivary glands, and the thyroid gland, as well as space-occupying and inflammatory processes of the neck. In addition, sonography enables targeted minimally invasive histology acquisition using ultrasound-guided biopsies. In this context, the examiner's comprehensive anatomical knowledge and clinical experience are of utmost importance for the quality of findings. This article provides an overview of the most important findings related to sonography of the neck and highlights the relevance of this imaging modality in the hands of the otorhinolaryngologist.
