PURPOSE In cases of thyroid toxic autonomous nodule, anterior projection of Tc-99m pertechnetate image shows a hot nodule that occupies most, or the entire thyroid lobe with near-total or total suppression of the contra lateral lobe. In this case is very difficult to distinguish toxic nodule from lobe agenesis. Our interest was to estimate and determinate the rate of radioactivity when the sour...

INTRODUCTION Thyroid paraganglioma is a very rare malignant neuroendocrine tumor. Immunohistochemical features of thyroid paraganglioma are helpful for the diagnosis. CASE REPORT A 69-year-old female came to hospital with the presence of a growing thyroid nodule of the left lobe. Ultrasonic neck examination showed 5 cm hypoechoic nodule in the left thyroid lobe. Thyroid scintigraphy showed a ...

Thyroid carcinoma (TC) combined with congenital hypothyroidism is rare. The synchronous occurrence of these two conditions is even rarer. We describe a patient with congenital hypothyroidism in whom hyperthyroglobulinemia and nodules developed despite adequate replacement therapy. Papillary TC was detected at age 19 years. Postoperative diagnostic scintigraphy showed increased uptake in the thy...

A 68-year-old man had a rapidly growing, painless neck mass, thought to be nodular goiter. Ultrasonography showed a giant, heterogeneous mass occupying the middle and superior poles and protruding outside of the left thyroid lobe. The results of the thyroid function tests were normal. Thyroid scintigraphy revealed a large hypoactive nodule in the left thyroid lobe. Complete surgical removal of ...

UNLABELLED In this study we compared whole body scintigraphy with Tc-99m-methoxyisobutylisonitrile (MIBI) and Iodine-131 NA (131I) for detection of residual and/or metastatic disease in well differentiated thyroid carcinoma. METHODS MIBI and I-131 scans were obtained in 60 patients. TSH measurements were done in all the patients prior to scintigraphy. RESULTS Out of 60 patients, for whom bo...

One hundred and thirty-one consecutive requests for thyroid scintigraphy were analysed to assess their diagnostic contribution to the subsequent medical management of the patient. Forty one per cent of requests were to investigate the presence of a clinically detectable solitary nodule and, of these, one fifth had hot nodules. Diffuse goitres accounted for 38% of all referrals, but in only two ...

The patient with a history of bone pain and muscle weakness, was thought to have oncogenic osteomalacia as a result of biochemical investigations and directed to Nuclear Medicine Department for a whole-body bone scintigraphy and 111In-octreotide scintigraphy. There was no focal pathologic tracer uptake, but generalized marked increase in skeletal uptake on bone scintigraphy. Octreotide scintigr...

Thyroid imaging is indicated to evaluate congenital hypothyroidism during newborn screening or in cases of a palpable thyroid mass in children and adolescents. This pictorial essay reviews the ultrasonography (US) of thyroid diseases in children and adolescents, including normal thyroid gland development, imaging features of congenital thyroid disorders (dysgenesis, [aplasia, ectopy, hypoplasia...
