OBJECTIVE The purpose of this study was to assess the rate of malignancy in thyroid nodules incidentally detected at sonography and to determine the diagnostic value of ultrasonography-guided fine needle aspiration cytology (USgFNAC) in thyroid nodules. METHODS Five hundred patients (84 men and 416 women) who had thyroid incidentalomas underwent USgFNAC at Konkuk University Hospital between A...
UNLABELLED Fine-needle aspiration (FNA) of the thyroid gland is a widely accepted and accurate method for triaging patients with thyroid nodules. Thyroid FNA suffers from a reporting confusion due to multiplicity of category terminologies. To address this, The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) was recently introduced for unifying the terminology and morphologic criter...
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...
INTRODUCTION The aim of this study was to conduct an audit of the sensitivity and specificity of ultrasound, fi ne needle aspiration cytology (FNAC) and frozen section in the evaluation of thyroid malignancies in our practice. MATERIALS AND METHODS The medical records of all the patients who underwent thyroid surgery in a tertiary institution's General Surgery Department between January 2005 ...
BACKGROUND The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) has standardized the reporting of thyroid cytology specimens. The objective of the current study was to evaluate the nationwide usage of TBSRTC and assess the malignancy rates in each category of TBSRTC in Korea. METHODS Questionnaire surveys were used for data collection on the fine needle aspiration (FNA) of thyroid...
INTRODUCTION Thyroid nodules are the most common endocrine condition treated by surgeons. The main purpose of the evaluation of a thyroid nodule is to rule out a carcinoma. Medical decisions concerning thyroid nodules are highly influenced by subjective beliefs. OBJECTIVE To assess the subjective probabilities of malignancy that are assigned to the clinical characteristics of a patient with a...
Anaplastic thyroid carcinoma is an uncommon, highly aggressive malignancy usually presenting in the elderly. An eighteen year old boy was recently diagnosed as anaplastic carcinoma of the thyroid. PET/CECT scan performed for staging, revealed a large FDG avid heterogeneously enhancing thyroid mass with bilateral jugular venous thrombosis, which also showed increase...
Thyroid cancer is the most common endocrine malignancy. This study surveys the pathologic characteristics of thyroid cancerin Mashhad and study of papillary carcinoma in more detail. In this retrospective study, 108 out of 197 cases of thyroid cancer were papillary in type (55%), with female to male ratio of 1.91 which is lower than current reports. The age at the time of diagnosis ranged ...
BACKGROUND High-resolution real-time ultrasonography (US) can detect characteristics of thyroid nodules, but the US differentiation between malignant nodules and benign nodules is not well described. HYPOTHESIS Ultrasonography is useful for predicting malignancy of thyroid nodules. DESIGN A retrospective study of 329 thyroid nodules (> or =5 mm) in 309 patients comparing US characteristics ...
BACKGROUND Metastatic malignancy to the thyroid gland is generally uncommon due to an unfavourable local thyroid micro-environment which impairs the ability of metastatic cells to settle and thrive. Metastases to the thyroid gland have however been reported to occur occasionally particularly if there has been disruption to normal thyroid tissue architecture. CASE PRESENTATION We report a pati...
