thyroid hemiagenesis can be associated with various thyroid pathologies such as papillary thyroid cancer or nodular goiter. however, we did not encounter any publication in the literature in which hemiagenesis could be observed together with retrosternal goiter. in this report, a thyroid hemiagenesis associated with a benign nodular goiter extending retrosternally is reported. a 59-year-old mal...

Thyrolipomas are rare capsulated mass lesions containing fat and thyroid tissue. We herein report the case of a 60-year-old man who had goitre for 10 years, with rapid enlargement of the gland during the last several months before presentation. Sonography, scintigraphy, CT, MR imaging, and sonography-guided fine needle aspiration were performed. Sonography and scintigraphy revealed an unusual m...

Abstract Parathyroid scintigraphy is an imaging technique that uses gamma-emitting radionuclide to locate hyperfunctioning parathyroid glands in patients with hyperparathyroidism. It valuable for preoperative assessment before parathyroidectomy, which a curative surgery most cases of primary hyperparathyroidism and some secondary There are several different techniques scintigraphy. In general, ...

Objective: To evaluate the contribution of 131I scintigraphy and ultrasonography to the prediction of malignancy in thyroid nodules with indeterminate cytology in euthyroid patients. Subjects and methods: The sample consisted of 102 patients with thyroid nodules, submitted to FNAC and presenting an indeterminate cytological diagnosis (follicular neoplasm). Results: Malignancy was observed in 19...

AIM To present a rare case of lingual thyroid detected using a hybrid of single photon emission computed tomography and standard computed tomography in a young woman with hypothyroidism. MATERIALS AND METHODS A 29-year-old woman was screened for autoimmune thyroid disorders in early pregnancy, and found to have subclinical hypothyroidism. No thyroid tissue was found in the anterior neck upon ...

OBJECTIVES This study is to assess the prognostic value of (99m)Tc-pertechnetate thyroid scintigraphy for predicting the outcomes of fixed low dose of radioiodine therapy (RIT) in a cohort of Chinese Graves' disease (GD) patients. MATERIALS AND METHODS This is a retrospective study of GD patients who received RIT with a single dose of radioiodine (5 mCi). All the patients received (99m)Tc-per...

BACKGROUND/AIM The major one among the procedures for evaluating changes in the thyroid nodules is fine needle aspiration biopsy (FNAB). Thyroid scintigraphy is commonly used in diagnostic algorithm of nodules. Less than 5% of examined nodules show to be malignant. Scintigraphically, nodules could be classified as functional and nonfunctional. It is estimated that the risk of malignancy in nonf...

Sir, I read with interest the article by Tindall, Griffiths & Penn.' They conclude that 'scintigraphy has been shown to be of little practical value in... patients with hypothyroidism and therefore should not be requested'. This does not hold true for neonates who are identified by newborn screening to have connatal hypothyroidism, i.e. thyrotrophin above 7 mU/l and T4 below 6 ug/dl, as defined...

Thyroid disorders are common worldwide and the biggest fear amongst most patients with neck swellings is thyroid cancer. We need simple techniques in our clinics to diagnose and treat patients with thyroid disorders in order to initiate the right treatment as well as to alleviate patient’s anxiety. Incomplete information and ignorance regarding these techniques prevents many clinicians to benef...

We studied the differentiation of thyroid nodules using fine-needle aspiration biopsy (FNA) and Tl-201 scintigraphy quantitative analysis. One-hundred and thirty-one thyroid nodules were examined: 83 follicular lesions (58 benign and 25 malignant lesions) and 48 non-follicular lesions (8 benign and 40 malignant lesions). During Tl-201 scintigraphy examinations, an early and a delayed image were...
