A 63-year-old woman presented with a history of hyperthyroidism symptoms over two years, referred for thyroid scintigraphy. In the hospital archives we have met her previous thyroid scintigraphy showing a hot nodule in the upper part of right thyroid lobe. However, her recent thyroid scintigraphy was showing only cold nodules but no hot nodule, giving an impression that she had some treatment t...

Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck r...

Thyroid hemiagenesis (THA) is a rare congenital anomaly. It occurs more frequently in the left lobe and predominantly in women. Most of the cases are asymptomatic. The most frequent associated thyroid disorders with THA are nontoxic nodular goiter and Hashimoto's thyroiditis whereas association of Graves' disease with THA is very rare. We present a man patient with THA and multinodular Graves' ...

i131 is a famous radio-iodine isotope in use for diagnosis and treatment of hyper functioning and cancerous thyroid gland. it is a nuclear reactor product; however nuclear reactor may be unavailable in some areas. replacement by i-124 may be possible, another iodine isotope producible by cyclotron; a system more available than reactor. here absorbed fraction of gamma and beta rays of i-124 thro...

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 ...

We present a case of an 89 year old female with a rapidly growing and painless neck mass over a period of five months. No evidence of dyspnea or dysphagia was identified. Her past medical history includes a multinodular goiter diagnosed two years ago with no follow-up. Palpation revealed a large, irregular, firm, tender and painless tumor mass in the right anterior neck. She was clinically euth...

background: the thyroid gland absorbs nearly all the iodine in the blood, independently of its isotopic composition. when a large enough activity of radioactive iodine like 131i, 132i, 133i is taken into the body, it can destroy the healthy thyroid gland cells as well as the cancer’s cells. in fact, as it is well known, some isotopes of iodine are used not only for acquiring thyroid images but ...
