“…In most cases, it was located anteromedial in relation to the CCA. 11,14 The resulting VN CSA readings showed good intra-and interrater agreement. Agreement was consistently stronger for the distal ML-that is, at the level of the thyroid gland, where a clearly discriminable (hyper)echoic rim around the nerve facilitated identification and analysis.…”

“…Voice change is a major complication of RF ablation, caused by damage to the recurrent laryngeal or vagus nerve (67, 68). In most cases, voice change is detected during or immediately after ablation.…”

“…the area of the thyroid nodule adjacent to the recurrent laryngeal nerve), may minimize voice changes (41, 52, 53). The cervical portion of the vagus nerve is located within the carotid sheath, usually between the common carotid artery and internal jugular vein, however a bulging large thyroid nodule may alter the location of the vagus nerve, making it closer to the thyroid nodule (67-70). We recommend checking the location of the vagus nerve before RF ablation.…”

Thermal ablation using radiofrequency is a new, minimally invasive modality employed as an alternative to surgery in patients with benign thyroid nodules and recurrent thyroid cancers. The Task Force Committee of the Korean Society of Thyroid Radiology has developed recommendations for the optimal use of radiofrequency ablation for thyroid nodules. These recommendations are based on a comprehensive analysis of the current literature, the results of multicenter studies, and expert consensus.

“…Running down the neck to the level of the thyroid gland, the vagus nerve can change its position relative to CCA. According to US studies, the vagus nerve has anatomical variations in its course (from lateral to anterior in 4.3–21.1% of cases and from lateral to medial in 1.2–1.6% of cases) (1315). In one study, there was even posterior variation of vagus nerve in 0.3% of the patients (Fig.…”

High-resolution Imaging of Neural Anatomy and Pathology of the Neck

The neck has intricately connected neural structures, including cervical and brachial plexi, the sympathetic system, lower cranial nerves, and their branches. Except for brachial plexus, there has been little research regarding the normal imaging appearance or corresponding pathologies of neural structures in the neck. The development in imaging techniques with better spatial resolution and signal-to-noise ratio has made it possible to see many tiny nerves to predict complications related to image-guided procedures and to better assess treatment response, especially in the management of oncology patients. The purposes of this review is to present imaging-based anatomy of major nerves in the neck and explain their relevant clinical significance according to representative pathologies of regarded nerves in the neck.
