BACKGROUND AND PURPOSE Accurate imaging characterization of a solitary thyroid nodule has been clearly problematic. The purpose of this study was to evaluate the role of the apparent diffusion coefficient (ADC) values in the differentiation between malignant and benign solitary thyroid nodules. MATERIALS AND METHODS A prospective study was conducted in 67 consecutive patients with solitary th...

Background: Extramedullary hematopoiesis is known to occur mainly in the organs of reticuloendothelial system. It is very rare for EMH to occur in thyroid nodule without any haematological abnormality. Case: A 71 year healthy male presented with 3 month history of dysphagia to solids. Clinical examination revealed thyroid nodule measuring 1 cm in diameter in right lobe of thyroid gland. FNAC wa...

Schwannoma of the thyroid bed is extremely rare, but is known to simulate a thyroid nodule. A retrospective review is reported of a 64-year-old female patient with a thyroid nodule who had been submitted to pre-operative fine-needle aspiration biopsy, judged inadequate, following which total thyroidectomy was performed. On histological examination, the nodule (in the thyroid bed) was found to b...

The thyroid nodule is an abnormal growth that forms lumps in the thyroid gland. Image processing opened a new era in the identification and diagnosis of nodules thyroids in which many of them are being found incidentally. It is estimated that between 4 to 10 % can be felt on physical examination, but the rest of them is determinate by ultrasound or another sophisticate image’s technique. The th...

In order to investigate whether serum growth differentiation factor 15 is associated with thyroid nodules in type 2 diabetes. We recruited 723 type 2 diabetic patients aged over 30 years who attended the clinic of Endocrinology of Xinhua Hospital from January 2013 to January 2015. Thyroid nodule was diagnosed by thyroid ultrasonographic examination. Serum growth differentiation factor 15, thyro...

Even though it is a rare event, most associations of thyroid carcinoma with subacute thyroiditis described in the literature are related to its granulomatous form (Quervain's thyroiditis). We present a patient with subacute lymphocytic thyroiditis (painless thyroiditis) and papillary thyroid cancer that was first suspected in an initial ultrasound evaluation. A 30-year old female patient who wa...

BACKGROUND In our daily experience, the differentiation between a cold and hot nodule is a very important factor for further clinical management of the patient. In this study, we compared the characteristics of incidentally found thyroid nodules detected on computed tomography (CT) to thyroid scintigraphy (TS). METHODS Diagnostic reports from chest CT with intravenous contrast and TS examinat...

IMPORTANCE There is wide variation in the management of thyroid nodules identified on ultrasound imaging. OBJECTIVE To quantify the risk of thyroid cancer associated with thyroid nodules based on ultrasound imaging characteristics. METHODS Retrospective case-control study of patients who underwent thyroid ultrasound imaging from January 1, 2000, through March 30, 2005. Thyroid cancers were ...

Background: Thyroid nodules commonly occur in the general population. They are often discovered incidentally. Fine needle aspiration biopsy (FNAB) is the usual practice for correctly diagnosing these nodules. Case presentation: The patient was a 24 year female. She presented with a thyroid nodule that was discovered incidentally as an otherwise asymptomatic neck mass. When her husband noticed t...

A 44-year-old woman presented with hyperthyroidism and a nodule in her thyroid. 1311-scintigraphy of the gland showed concentration of the tracer within the nodule and suppressed activity in the rest of the gland. Histology of the resected thyroid proved the nodule to be a papillary carcinoma. The presence of carcinoma within an autonomous hyperactive thyroid in a patient with hyperthyroidism h...
