An important diagnostic tool for the evaluation of thyroid disease, thyroid ultrasound has recently become available for use in surgical offices. The purpose of this report is to determine the lesional sensitivity of office-based thyroid ultrasound and its impact on clinical decision making. Surgical office-based thyroid ultrasound was performed on 49 consecutive patients who presented with thy...
Thyroid sonography as an effective tool to discriminate between euthyroid sick and hypothyroid dogs.
The diagnosis of canine hypothyroidism and its differentiation from euthyroid sick syndrome still is a major diagnostic challenge. In this study, ultrasonography was shown to be an effective tool for the investigation of thyroid gland diseases. Healthy control dogs (n = 87), dogs with euthyroid sick syndrome (n = 26), thyroglobulin autoantibody-positive (TgAA-positive, n = 30) hypothyroid dogs,...
BACKGROUND In the most patients with differentiated thyroid carcinoma (DTC), recurrent disease occurs in the neck region, but the usefulness of neck ultrasound (US) in its diagnosis is not clear. The aim of this study was to evaluate the significance of US in the detection of neck recurrence in low-risk DTC patients at first follow-up visits. MATERIAL AND METHODS A total of 32 patients, who h...
We report a case of severe hypothyroidism with nongoitrous, autoimmune thyroiditis and pituitary hyperplasia in a 13-year-old boy, who presented with sudden palsy on the left side of his face. Prednisolone and antiviral medication was administered. However, the facial palsy did not improve completely. The medications were replaced with thyroxine, and the facial palsy recovered. Endocrinological...
Background: Fine Needle Aspiration (FNA) of thyroid gland has greater sensitivity as compared to other diagnostic modalities for thyroid nodules. The present study was conducted to compare the sonographic findings of cold thyroid nodules with cytologic changes. Materials and methods: For 219 patients, sonography of thyroid nodules was performed by 7.5MHz probes and the following changes were r...
We report here on an extremely rare case of an intrathyroidal branchial cleft cyst. Intrathyroidal branchial cleft cyst is rare disease entity and it has nonspecific findings on sonography, so the diagnosis of the lesion is very difficult. However, during aspiration, if pus-like materials are aspirated from a thyroid cyst, we should consider the possibility of intrathyroidal branchial cleft cys...
Sir, I read with interest the article by Tindall, Griffiths & Penn.' They conclude that 'scintigraphy has been shown to be of little practical value in... patients with hypothyroidism and therefore should not be requested'. This does not hold true for neonates who are identified by newborn screening to have connatal hypothyroidism, i.e. thyrotrophin above 7 mU/l and T4 below 6 ug/dl, as defined...
A PTMC is defined as a thyroid papillary cancer that measures < or =10 mm in the greatest diameter. The detection rate for a PTMC has increased because of the worldwide use of high-resolution sonography and US-FNAB. We report a case of a 1-mm-diameter PTMC confirmed at thyroidectomy for which the cytologic diagnosis had an important role in deciding the extent of surgery (ie, either a total thy...
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...
