Parathyroid gland carcinoma is a rare malignancy. The tumor is mostly functioning, causing severe hyperparathyroidism, with high serum calcium level and severe bone disease. Non-functioning parathyroid carcinomas are extremely rare. We report on a 60-year-old male patient admitted to ENT Department due to a large neck tumor mass compressing the thyroid and trachea. Preoperatively, thyroid hormo...
Thyroid dysfunction is relatively common, with hypothyroidism in women reported to have a prevalence of 4.1 per 1000 population, and 0.8 per 1000 having hyperthyroidism. Unlike hypothyroidism which becomes more prevalent with age, Grave’s disease – autoimmune hyperthyroidism – seems to not do this, with the incidence remaining relatively steady at 1 in 1000 per year between the ages of 35 and 6...
Terms such as retrosternal, substernal, and intrathoracic have been used to define an extension of >50% the thyroid gland beyond thoracic inlet. The reported incidence retrosternal goiters is highly variable, ranging from 1% 45% thyroidectomies in studies with different defining criteria. Forgotten goiter lacks any parenchymatous or vascular connection cervical may represent remnants a partiall...
Lingual thyroid is a developmental anomaly caused by undescended thyroid tissue at the base of the tongue. Lingual thyroid is found predominantly in females and comprises 90% of ectopic thyroid tissue (1). In the majority of patients, the lingual thyroid is the only functioning thyroid gland tissue. Therefore early diagnosis with imaging techniques is clinically important to avoid permanent hyp...
OBJECTIVE To determine the utility of ultrasonography as a sole diagnostic study in the preoperative preparation of patients with presumed thyroglossal duct cysts. DESIGN Retrospective chart review. SETTINGS Children's Memorial Hospital, Chicago, Ill. PATIENTS Forty-five pediatric patients with midline masses. MAIN OUTCOME MEASURE Accuracy in the determination of a normally positioned t...
Thyroid gland metastatic tumors are rare in clinical practice. Clear cell RCC is one of common metastatic tumors to thyroid. We here reported a case of incidentally found clear cell renal carcinoma metastasis to the thyroid gland 3 years after nephrectomy, in the thyroidectomy procedure performed for the patient due to the thyroid enlargement caused by multinodular goiter. A 65-year-old Iranian...
Introduction: Dental panoramic radiography (DPR) is one of the most frequent diagnostic X-ray procedures, the application of which is currently on a growing trend. During DPR, several radiosensitive tissues, such as the lens of the eyes, parotid gland, and thyroid gland, contribute to the radiation field, and it is necessary to monitor their received dose. The aim of t...
We characterized the scintigraphic and sonographic appearance of the thyroid gland in clinically normal horses to establish the value of these modalities for assessment of the thyroid gland in this species. Horses were divided into two age groups. One group consisted of eight horses between 3 and 10 years of age and the other of seven horses between 11 and 20 years of age. Total T4 concentratio...
Three hormones, thyroxine (3,5,3 ,5 -tetraiodothyronine, or T4), triiodothyronine (3,5,3 -triiodothyronine, or T3), and calcitonin (see Chapter 66) are secreted by the thyroid gland. The hormones T4 and T3 are iodinecontaining amino acid derivatives and are unique in that they have no discrete target tissue. Every tissue in the body is affected in some way by thyroid hormones, and almost all ce...
Seasonal changes of the thyroid gland structure and hormones secretion was examined in yellowfin seabream (Acanthopagrus latus) in the northwest of Persian Gulf (Musa creek). Thyroid gland composed of follicles scattered around the ventral aorta, near the gills. Follicular cells varied according to secretion of the gland during warm and cold seasons. Thyroid hormones (Triidothyronine [T3] and ...
