PURPOSE The characteristics of fetal thyroid on magnetic resonance (MR) imaging, including normal thyroid and disorders other than goiter have not been fully evaluated. Our aim was to assess fetal thyroid using three dimensional (3D) gradient echo (GRE) T1-weighted MR imaging and to examine the usefulness of this modality. MATERIALS AND METHODS The study included 27 3D GRE T1-weighted images ...

Developmental structural abnormalities of the Thyroid gland are relatively rare and can be categorized into; Agenesis of Thyroid gland, Dysgenesis of the Thyroid, Abnormalities due to persistence of the Thyroglossal Duct. The aim is to analyse clinicopathological aspects of Developmental anomalies of Thyroid at a Tertiary care hospital for Head and Neck diseases. An analysis of 2977 consecutive...

The classic TS phenotype includes short stature, gonadal dysgenesis with primary amenorrhea and hypergonadotropic hypogonadism, facial and body dysmorphisms, skeletal abnormalities, cardiovascular and renal malformations, and predisposition to autoimmune diseases, such as thyroid diseases, diabetes mellitus, celiac disease, and vitiligo.21 Short stature is always present and is caused by severa...

Permanent primary congenital hypothyroidism (CH), the commonest cause of preventable intellectual disability, is due to defects in the embryonic development of the thyroid in the vast majority of cases. These defects are collectively called thyroid dysgenesis. The thyroid may be absent (athyreosis) but, more commonly, a sublingual thyroid ectopy without lateral lobes, is the only thyroid tissue...

OBJECTIVE Although the association between Down's syndrome (DS) and thyroid dysfunction is well recognized, the cause of this condition is not known. METHODS Hospital records of patients with DS and hypothyroidism referred to our clinic were retrospectively reviewed. Initial thyroid hormone and thyrotropin (TSH) levels, age at admission, initial anthropometric measurements, age at the beginni...

PURPOSE To validate the use of the ratio between the total transverse diameters of the thyroid lobes (Th) and the width of the trachea (Tr)-the Th:Tr or Yasumoto ratio-as a sonographic method for estimating thyroid size, and to determine reference values for this ratio and for thyroid volume in neonates. METHODS In this cross-sectional study, we evaluated thyroid size according to the Yasumot...
