“…Besides these seven children, there were 7 children already under follow-up with IET, diagnosed by A.K. using sonographic criteria described in the literature [4][5][6][7]. All 14 children (6 female, 8 male, mean age 6±3.0 range 2-12) with a total of 16 lesions were included in the follow-up phase of the study.…”

Intrathyroidal ectopic thymus in children: a sonographic survey

et al. 2017

Aims: Intrathyroidal ectopic thymus (IET) is being increasingly reported in the radiology literature. Most of the reports are of individual cases or small series and prevalence and natural course of the pathology is not well known. The purpose of this study is to establish the prevalence of IET in children and report long term follow-up results.Material and methods: In 180 children who were examined by ultrasound (US) for other reasons, 7 patients were indentified with IET. Together with the other seven children who were already under follow-up for IET (diagnosed using US criteria), these 14 patients were followed up with US for 30 months. Size, shape, location, echotexture and internal echoes of the lesions were evaluated.Results: There were 16 lesions in 14 children. The most common appearance was a fusiform hypoechoic lesion, with punctate and linear internal echoes and well-defined but slightly irregular borders located posteriorly in the lower thirds of the thyroid. In follow-up, there were no changes in echotexture, shape or border. In 3 patients, the lesion became slightly smaller, in a 10-year-old boy slightly larger, and in an 11-year old boy the lesion disappeared. In a patient with bilateral lesions, one lesion slightly decreased in size.Conclusions: IET in children may be more common than thought. Its growth reflects that of a normal thymus. Awareness of this entity is important in order not to misdiagnose them, especially as papillary cancer, and to prevent unnecessary interventions.

“…who were found to have no goiter or thyroid nodules on palpation of the thyroid gland, were euthyroid, The data were adjusted for age on the basis of the standard population data from the National Census in 2010 The data were adjusted for age on the basis of the standard population data from the National Census in 2010 in 35 individuals (12.2%) and smoothly demarcated hypoechoic nodules and an intrathyroid ectopic thymus were seen in 9 individuals (3.1%) [19]. Thus, while the incidence rate of nodules differs among reports, nodules > 5 mm in diameter were slightly predominant in all reports.…”

“…Most cystic thyroid lesions are pseudocysts from hyperplastic nodules that have undergone extensive degeneration, necrosis and hemorrhage into the parenchyma with fluid accumulation (fig 1) [3]. Colloid cysts may contain bright echogenic foci with comet-tail artifacts caused by the presence of microcrystals (fig 2) [4][5][6].…”

Thyroid Ultrasound: State of the Art. Part 2 – Focal Thyroid Lesions

Accurate differentiation of focal thyroid nodules (FTL) and thyroid abnormalities is pivotal for proper diagnostic and therapeutic work-up. In these two part articles, the role of ultrasound techniques in the characterization of FTL and evaluation of diffuse thyroid diseases is described to expand on the recently published World Federation in Ultrasound and Medicine (WFUMB) thyroid elastography guidelines and review how this guideline fits into a complete thyroid ultrasound exam.
