This review describes the frequency of solitary thyroid nodules and their relationship to thyroid cancer. The importance of selecting patients appropriately for surgical excision is stressed. The factors predisposing to nodule formation and to a nodule being malignant are reviewed with emphasis that prior radiation exposure does not appear to increase the likelihood that a given nodule harbors ...
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...
Nodules have been reported to be present in 50% of thyroids in autopsy series.1 Aminority of these thyroidnodules arepalpable, leaving a broad opportunity for discovery of incidental thyroid nodules through imaging tests performed for other indications, including carotid ultrasound and chest computed tomography. Indeed, detection of asymptomatic thyroid nodules as incidental findings on radiolo...
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...
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...
We report an extremely rare case of papillary thyroid microcarcinoma (PTMC) in the thyroid Epub ahead of print pyramidal lobe (TPL). A 48-year-old woman underwent ultrasound-guided fine-needle aspiration for a small thyroid nodule in the right lobe in local clinic, and it revealed a malignant cytology. On preoperative ultrasonography for tumor staging in our hospital, another small suspiciously...
Thyroglossal cysts are the most frequent neck malformation in children. They are usually located in the anterior midline near the hyoid bone, and may appear at the lingual (2.1%) or suprasternal (12.9%) level. Their presentation as a solitary thyroid nodule (STN) has been described in the literature and poses a challenge in the differential diagnosis of thyroid disorders in children. We present...
INTRODUCTION We report the case of an incidental solitary renal cancer cell (RCC) thyroid metastatic nodule treated by thyroidectomy. PRESENTATION OF CASE A 53 year male presented with a solitary, asymptomatic thyroid nodule. He was treated with left nephrectomy 1 year before for a RCC. Radiological standard follow-up was negative for secondary lesions but ultrasound (US) 12 months after surg...
