Thyroid scintigraphy is now rarely used in the work-up of a thyroid nodule except in the presence of a low TSH value. Therefore, autonomously functioning thyroid nodules (AFTNs) with a normal TSH value are diagnosed only in the rare medical centers that continue to use thyroid scan systematically in the presence of a thyroid nodule. In this review, we discuss the prevalence of AFTN with a norma...
Solitary thyroid nodules are commonly seen in surgical outpatient clinics. A detailed history and a careful physical examination are essential. In the management of the solitary thyroid nodule, fine needle aspiration cytology has become the cornerstone investigation. Ultrasound cannot differentiate between benign and malignant nodules, however is useful in the follow-up period to identify any f...
OBJECTIVES To evaluate the positive predictive value of a thyroid nodule being malignant when categorized as atypical, and to determine the prognostic implications of specific cytopathological features. DESIGN Retrospective review of consecutive patients undergoing thyroid surgery following fine-needle aspiration biopsy (FNAB) of thyroid nodules. SETTING Academic teaching hospital in Toront...
Background: In this study, we investigated the diagnostic power of ultrasound in the diagnosis of malignancy in thyroid nodules in Iranian patients. For this purpose, we examined the relationship between ultrasound findings and pathology findings. Methods: The present study is a retrospective study. The patients with a diagnosis of thyroid nodules who underwent ultrasound and FNA, were include...
Introduction and Aim: Ultrasound of the thyroid gland is a routine procedure. Nodules are most common disorders seen analyzed by ultrasound. The study purpose was to show how accurate ultrasonography at identifying benign from malignant nodules using (Thyroid Imaging Reporting Data System TIRADS) categories. High-frequency scanning neck glands offers useful information anatomical images. Materi...
Ultrasonography (US) is the single-most valuable imaging modality in the evaluation of the thyroid gland. This review discusses the US appearances of thyroid nodules, emphasizing sonographic features associated with potentially malignant or, at the other end of the spectrum, likely benign nodules. Diffuse thyroid abnormalities have also been reviewed. The technique of ultrasound-guided fine-nee...
The thyroid nodule is a frequent cause of primary care consultation. The prevalence of a palpable thyroid nodule is approximately 4-7%, increasing up to 67% by the incidental detection of nodules on ultrasound. The vast majority are benign and asymptomatic, staying stable over time. The clinical importance of studying a thyroid nodule is to exclude thyroid cancer, which occurs in 5 to 10% of th...
INTRODUCTION Ultrasound elastography (US-E) is a helpful tool for the diagnosis of thyroid cancer. In acromegaly, multinodular goiter is a common occurrence while the prevalence of thyroid cancer is still matter of debate. Our aims were to evaluate thyroid nodules in acromegaly and to assess the accuracy of US-E in providing information on their nature (benign vs. malignant) using cytological a...
INTRODUCTION Small cell lung carcinoma frequently metastasizes to lymph nodes, liver, adrenal glands, bone, brain and pleura. Metastasis of small cell lung cancer to the thyroid gland is extremely rare. CASE PRESENTATION A 55-year-old Turkish man presented with a mediastinal mass intermingled with mediastinal lymphadenopathy, measuring 11cm in total, and encasing superior vena cava and deviat...
