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.

Transverse ultrasonography images of bone and cartilaginous structures.A. Hyoid bone (arrowheads) appears as hyperechoic, inverted U-shaped linear structure with posterior acoustic shadowing. (B) Thyroid cartilage (arrowheads) has inverted V shape, and (C) cricoid cartilage (arrowheads) has arch-like appearance with homogeneous hypoechogenicity.

Figure 19: Transverse ultrasonography images of bone and cartilaginous structures.A. Hyoid bone (arrowheads) appears as hyperechoic, inverted U-shaped linear structure with posterior acoustic shadowing. (B) Thyroid cartilage (arrowheads) has inverted V shape, and (C) cricoid cartilage (arrowheads) has arch-like appearance with homogeneous hypoechogenicity.

Mentions: Bone and cartilage are the center of the thyroid and neck structures. Bony structure includes the hyoid bone and vertebrae, and appears as a bright hyperechoic linear structure with a hypoechoic acoustic shadow underneath. The cartilaginous structure includes thyroid and cricoid cartilages, and is homogeneously hypoechoic on US. However, it may be heterogeneous if it contains calcifications (Fig. 19) (61).
