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.

Mentions: Traumatic neuroma is caused by non-neoplastic proliferation of nerve tissue that occurs at the end of an injured nerve after trauma or surgery. It can be identified by US in 17.8% of patients after neck dissection (24). Because the traumatic neuroma usually arises from branches of the cervical plexus after neck dissection, it can be identified along the course of the cervical plexus (Fig. 14). Therefore, it is important to understand the course of the cervical plexus and its related anatomy for an accurate diagnosis of traumatic neuroma.
