Two hundred and three patients with single thyroid nodules were referred for radioactive scan of the thyroid. Solitary "cold" nodules were identified in 130 patients and 68 of these patients came to surgery. Of this group, 12 patients were found to have carcinoma. There was no obvious selection process which distinguished the 68 patients who underwent surgery from the 62 who did not. There is a...

In patients with morphological alterations of the thyroid, both physical examination (inspection and palpation) imaging studies continue to be cornerstone for their evaluation, treatment, long-term follow-up. The realization anatomical figures, obtained by means a thyroid morphology delineation technique, is proposed as an additional exploratory intervention strategy in initial clinical evaluat...

INTRODUCTION Measuring thyroid stimulating hormone levels alone may be insufficient to appropriately evaluate thyroid function. Reduced thyroid stimulating hormone levels associated to normal/reduced FT4 levels should prompt investigation of pituitary function, on suspicion of hypopituitarism. Pituitary macroadenomas are the most common cause of hypopituitarism; among these, macroprolactinomas ...

Fluorodeoxyglucose (FDG) whole body positron emission computed tomography (PET-CT) detects clinically occult malignancy. The aim of this study was to assess the prevalence and significance of focal thyroid 18F - fluorodeoxyglucose uptake. A retrospective review of all patients who had FDG PET-CT examinations, in a single tertiary referral centre was performed. PET scan findings and the final pa...

—An 82-year-old female patient with hypothyroidism and Hashimoto’s thyroiditis noted three years ago to have a small asymmetric goiter (left > right). Nevertheless, a rapid growth of the thyroid over 3-6 months caused dysphagia and shortness of breath. Ultrasound and a thyroid gammagram showed an image consistent with multinodular goiter with a hyperfunctioning nodule in the right lobe. Due to ...

RATIONALE Thyroid hemangioma is benign and associated with fine-needle aspiration (FNA) biopsy or trauma in most cases. Its differential diagnosis is very difficult. PATIENT CONCERNS We presented the case of a 48-year-old man complained of slowly progressed swelling in the anterior neck for 20 years. DIAGNOSES Ultrasound and CT scan revealed a hypoechogenic and heterogeneous mass measuring ...

This paper starts with the local textural information of ultrasound thyroid images. The recent feature extraction methods are presented with the different application areas. The basic objective of this study is to identify and represent the performance of a novel approach for texture characterization of thyroid ultrasound images. The method proposed here should reduce the uncertainty produced b...

We report a rare event of old hemorrhage into a thyroid causing respiratory distress. A 67-year-old man with chronic cough and recent dysphagia was found to have a retrosternal mass extending into the visceral mediastinum on chest roentgenogram. A computed tomographic (CT) scan confirmed eggshell callcification, which was 53 x 53 x 80 mm in size a retrosternal thyroid mass and revealed signific...

Lymph node metastasis of nasopharyngeal carcinoma follows an orderly pattern, and diagnosis of nasopharyngeal carcinoma is often made by lymph node biopsy. In the present study, following neck palpation, ultrasonography and cervical computer tomography, a 52-year-old female patient with thyroid adenoma and enlarged cervical lymph nodes was misdiagnosed as thyroid carcinoma without undergoing pr...
