Thyroid hemiagenesis (TH) is a rare congenital anomaly that is usually asymptomatic. Functional disorders of the thyroid make the patient symptomatic. TH is usually and incidentally established during evaluation of patients with symptomatic thyroid pathology. We report the case of a patient of TH who became symptomatic with hyperactivity of the gland. The patient presented with signs and sympto...

A 44-year-old euthyroid woman had two palpable nodules in the thyroid gland. 123I thyroid scintigraphy showed a hot nodule in the right lobe and a cold one in the left lobe. Total thyroidectomy was performed, and histopathologic examination revealed that both tumors contained papillary carcinoma. Thus, hot nodules on a thyroid scintigram with 123I do not necessarily preclude malignancy.

To the Editors, A 67­year­old woman presented with a solitary nodule in the left lobe of the thyroid gland. She was clinically and chemically euthyroid. Thyroid function test showed serum free thyroxine 1.01 ng/dl (normal 0.83–1.44 ng/dl), free triiodothyronine 1.91 pg/ml (normal 1.73­3.20 pg/m) and thyrotropin 1.25 mIU/L (normal 0.49­4.67 mIU/L). An ultrasound examination of thyroid gland show...

papillary microcarcinoma of thyroid (pmc) as a variant of papillary carcinoma less than 1 cm in size is a new clinicopathological entity, with high incidence and good prognosis. there are many differences between pmc and clinically apparent papillary thyroid carcinoma. also, there are some pmc case reports with unusual metastasis and aggressive courses. prognostic factors are age, size and morp...

echinococcosis, although eradicated in many countries, is still widespread in communities where agriculture is dominant. cystic hydatidosis is a significant public health problem in the regions with endemic echinococcosis. the hydatid cysts tend to form in the liver or lung, but may also be found in other organs of the body such as brain, heart, and bone, while thyroid gland involvement is rath...

Thyroid hemiagenesis (TH), very rare congenital anomaly, is generally asymptomatic. We report two cases of TH with hyperthyroidism. Case One. The patient presented with signs and symptoms of thyrotoxicosis. Physical examination revealed asymmetric nodular goitre at right lobe. Biochemical analysis revealed the diagnosis of hyperthyroidism. Ultrasound showed multinodular hypertrophy in the right...

Although several reports have defined normal thyroid volume depending on either age or body surface, there are no sequential reference values on childhood thyroid volume evaluated by using ultrasonography and epidemiological analysis in Japan. The aim of the present study was to establish updated reference values for thyroid volume by ultrasound examination and epidemiological analysis in 0-19 ...

Introduction: Cauda equina secondary to metastatic follicular thyroid cancer of the lumbosacral area is a rare entity.   Case Report: We report an unusual case of a 52-year-old male who presented with backache, lower limb weakness, and perianal numbness. A CT-scan of the lumbosacral area showed an enhancing mass at the L4, L5 and S1 vertebrae. Histopathology after excision revealed a metast...

In the course of a study of the factors which determine regeneration of the thyroid gland and the fate of thyroid transplants, we compared autotransplantation of one thyroid lobe in cases in which the second lobe had been left intact and in which it had been extirpated previous to the transplantation. We also compared the fate of autotransplants and homoiotransplants at various stages. In an an...
