A case of parasitic thyroid nodule is presented. The patient was a non symptomatic 53-year-old white woman, on irregular course of L-thyroxine to treat hypothyroidism due to Hashimoto's thyroiditis. Without a history of thyroid trauma or surgery, she presented a 1.6 x 0.7 x 0.5cm right pre-laryngeal lymph node-like mass which, on ultrasonography, appeared distinct from the gland. TSH, thyroid p...

CLINICAL SUMMARY Mediastinal enlargement and a solitary pulmonary nodule were detected on a 68-year-old male patient’s chest radiograph during routine annual examination. Computed tomography and magnetic resonance imaging revealed a lobulated, solid, and well-demarcated right paratracheal mass 6 3 4 3 4 cm in dimension (Figure 1). The solitary, heterogeneous parenchymal mass located in the righ...

Approach to incidental thyroid nodules on imaging Thyroid cancer is the fastest increasing cancer in the USA. An exponential increase in incidence of thyroid cancer has been partly attributed to an increased work-up of incidentally detected thyroid nodules on imaging, especially ultrasound and CT. Excessive workup of incidental thyroid nodules and overdiagnosis of subclinical cancers is a costl...

In 30 patient with single cold thyroid nodule and normal thyroid function tests, 99mTc-MIBI scan is performed. The nodules are divided to hot (10), Warm (12) and cold (8). FNA reported papillary Ca in 4, suspicious follicular neoplasm in 3 and 23 benign lesions. 7 patients were operated on and had final pathology reports (4 papillary Ca and 3 benign lesions). All the nodules with no MIBI ...

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 ...

BACKGROUND AND OBJECTIVES The finding of a thyroid nodule is a very common occurrence in clinical practice. Management of thyroid nodules requires a multidisciplinary approach that may be eased by a high-resolution thyroid nodule clinic. We report our clinical experience and outcomes in a high-resolution thyroid nodule clinic. PATIENTS AND METHODS All patients referred to Virgen de la Victori...

A 63 years old woman with Hashimoto's thyroiditis, on thyroxin treatment presented imaging studies concordant with a multinodular goiter, a "hot" nodule in the left lobe and partial suppression of the right lobe. After thyroxin withdrawal overt hypothyroidism developed, yet the patient's imaging studies were not altered. This is a case of hypothyroidism in a patient with Hashimoto's thyroiditi...

There are many imaging modalities available for studying thyroid and parathyroid masses. For the thyroid gland, the demonstration of a hyperfunctioning or purely cystic mass by scintigraphy and ultrasound reassures that a palpable nodule is not cancer. Solitary, cold, or solid nodules often requires biopsy because of suspicion of malignancy. Metabolic and inflammatory disorders are imaged best ...

introduction: considering the influence of geographical, genetic and ethnic factors on the prevalence of thyroid pathological lesions, this study was performed to assess the prevalence of pathological lesions in thyroid autopsic samples obtained from adult cadavers of isfahan forensic medical center. material and methods: in this study, 202 thyroid glands from cadavers with no evidence of thyro...
