ABSTRACT Thyroid gland has three main embryological remnants: pyramidal lobe, tubercle of Zuckerkandl and thyrothymic remnants. They are commonly missed or misidentified during dissection. Each of these remnants plays a critical role in thyroidectomy as they help to identify the relevant anatomy and therefore help prevent accidental damage to other structures in close proximity during dissection. In this article, we describe the current knowledge of each of these remnants and their significance in thyroidectomy. Conclusion It is important that all these remnants are objectively looked for and removed during surgery in order to prevent recurrences.

AbstractThe thyroid gland is an important and easily approachable endocrine gland, situated in the lower part of anterior aspect of neck. The Levator glandulae thyroidea (LGT) is a fibro-musculo-glandular band. It is usually present on the left side connecting the pyramidal lobe of thyroid gland to the hyoid bone. During the routine dissection of neck it was observed that the LGT was present on the right side of midline of neck extending from pyramidal lobe of the right side of isthmus of thyroid gland to the inferior border of hyoid bone. It was muscular throughout with 6.5cm in length, 1.5cm breadth and 1.75mm in its thickness. This is a rare variation in the morphology and situation of LGT observed for the first time. The presence of LGT and its anatomical variations gain importance in the pathologies related to thyroid gland and their treatment modalities.

We investigated two structures that are in close association with the pyramidal lobe of the thyroid gland. Our investigation was performed using microdissection and histological examination in 106 human postmortem specimens. The first investigated structure was identified as the thyroid fibrous band that was present in 28.3% of cases. This band was always associated with the pyramidal lobe (which was significantly longer and thicker when associated with this band) and it had a constant hyo-pyramidal extension; it was located close to the midsagittal plane and predominantly composed of dense irregular connective tissue. The second investigated structure was the levator glandulae thyroideae muscle, which was associated with the pyramidal lobe in only 13.6% of cases. This muscle had a double extension, hyo-pyramidal and laryngo-pyramidal, located farther from the midsagittal plane, it was longer and thinner than the thyroid fibrous band and predominantly composed of striated muscle fibers. We confirmed our hypothesis that the thyroid fibrous band, which may be considered as the partial fibrous remnant of the thyroglossal duct and levator glandulae thyroideae, and which may be considered as infrahyoid or laryngeal muscle, are two different structures of the thyroid gland.

Sensitive Marker

Clinically, a diffuse, firm goiter with pyramidal lobe enlargement, and without signs of thyrotoxicosis, should suggest the diagnosis of Hashimoto's thyroiditis (HT). The association of goiter with hypothyroidism is almost diagnostic. The thyroid stimulating hormone (TSH) is the sensitive marker of hypothyroidism and diagnosis of subclinical hypothyroidism. Thyroid perioxidase antibodies (TPO-Ab) and, less frequently, thyroglobulin antibodies (Tg-Ab) are elevated in the serum of patients with HT. Ultrasound may display an enlarged gland with normal texture, focal, or diffuse glandular enlargement with coarse, heterogenous, and hypo-echoic pattern, or a suggestion of multiple ill-defined micro-nodules. Color Doppler shows extensive hyper-vascularity. Histologically, the thyroid gland shows diffuse lymphocytic and plasma cell infiltration with formation of lymphoid follicles. Atrophy of the thyroid parenchyma is usually evident. It also reveals scant colloid, and a few epithelial cells, which may show Hurthle cell change. This chapter explores the diagnosis of Hashimoto's disease.
