Ultrasonography-Based Thyroidal and Perithyroidal Anatomy and Its Clinical Significance.

Ha EJ, Baek JH, Lee JH - Korean J Radiol (2015)

Bottom Line: For a safe and effective US-guided procedure, knowledge of neck anatomy, particularly that of the nerves, vessels, and other critical structures, is essential.Therefore, the aim of this article was to elucidate US-based thyroidal and perithyroidal anatomy, as well as its clinical significance in the use of prevention techniques for complications during the US-guided procedures.Knowledge of these areas may be helpful for maximizing the efficacy and minimizing the complications of US-guided procedures for the thyroid and other neck lesions.

ABSTRACT
Ultrasonography (US)-guided procedures such as ethanol ablation, radiofrequency ablation, laser ablation, selective nerve block, and core needle biopsy have been widely applied in the diagnosis and management of thyroid and neck lesions. For a safe and effective US-guided procedure, knowledge of neck anatomy, particularly that of the nerves, vessels, and other critical structures, is essential. However, most previous reports evaluated neck anatomy based on cadavers, computed tomography, or magnetic resonance imaging rather than US. Therefore, the aim of this article was to elucidate US-based thyroidal and perithyroidal anatomy, as well as its clinical significance in the use of prevention techniques for complications during the US-guided procedures. Knowledge of these areas may be helpful for maximizing the efficacy and minimizing the complications of US-guided procedures for the thyroid and other neck lesions.

Horner syndrome after RF ablation of left thyroid nodule.On transverse (A) and longitudinal (B) ultrasonography, middle cervical sympathetic ganglion (arrowheads) are seen abutting lateral margin of ablated thyroid nodule. Horner syndrome was developed immediately after RF ablation in this patient. RF = radiofrequency

Figure 10: Horner syndrome after RF ablation of left thyroid nodule.On transverse (A) and longitudinal (B) ultrasonography, middle cervical sympathetic ganglion (arrowheads) are seen abutting lateral margin of ablated thyroid nodule. Horner syndrome was developed immediately after RF ablation in this patient. RF = radiofrequency

Mentions: The clinical significance of the middle CSG during the procedures could be variable depending on its location relative to the CCA. Lateral to the CCA, the middle CSG could be misinterpreted as a metastatic lymph node, possibly causing unnecessary FNA or CNB. It is vulnerable to thermal injury during RF ablation of recurrent tumors at the lateral neck. Medial to the CCA, the middle CSG closely adjacent to the thyroid gland, and could be damaged during RF ablation near the lateral margin of benign thyroid nodules (Fig. 10) (404344).
