Pitfalls in the diagnosis of thyroid dysgenesis by thyroid ultrasonography and scintigraphy

Pitfalls in the diagnosis of thyroid dysgenesis by thyroid ultrasonography and scintigraphy.

OBJECTIVES We aimed to investigate the reliability of thyroid ultrasonography (US) and scintigraphy in determining the type of thyroid dysgenesis (TD). METHODS The study included 82 children (8.0±5.6 years) with a diagnosis of TD by thyroid scintigraphy with (99m)Tc and/or US. The patients were re-evaluated 6.0±5.1 years after the diagnosis. Thyroid US was performed in all cases, regardless o...

Thyroid Ultrasonography: Pitfalls and Techniques

Thyroid ultrasonography (US) plays a key role in the diagnosis and management of thyroid-related diseases. The aim of this article was to illustrate various pitfalls that can occur in utilizing thyroid US and techniques to prevent them. In this article, we present cases demonstrating the common pitfalls associated with US equipment, performance, normal thyroid structures, misinterpretations, an...

Thyroid and parathyroid scintigraphy

Epidemiology of thyroid dysgenesis: the familial component.

The pathophysiology of thyroid dysgenesis remains unclear and, until recently, this disorder was generally regarded as sporadic. However, a small but significant proportion of familial cases have been identified (2%) through the study of subjects with congenital hypothyroidism, and more recent work has revealed an even higher proportion of familial thyroid dysgenesis in both symptomatic and asy...

Comparative thyroid gland volume by two methods: Ultrasonography and planar scintigraphy

BACKGROUND Knowledge of thyroid gland volume plays a key role in the treatment of thyroid diseases by radioactive iodine 131I. Radioiodine therapy is a routine procedure of treatment hyperthyroidism for over 50 years. MATERIAL/METHODS Today modern diagnostic has a number of medical diagnostics instruments whose using to estimate of thyroid volume. Undoubtedly these method we can include a ult...
