Thyroid hemiagenesis is a rare congenital anomaly in which one lobe of thyroid gland fails to develop. It is much rarer in males. There is a higher incidence of associated thyroid disorders in patients with thyroid hemiagenesis; therefore early and prompt diagnosis is important for children. We present the ultrasonographic and scintigraphic findings of thyroid hemiagenesis in an eight-year-old-boy. On ultrasonography (US), left lobe of the thyroid gland could not be demonstrated and the right lobe showed minimal hyperplasia. Its echogenicity was normal and no nodule was seen. On thyroid scintigraphy, left lobe of thyroid gland or any ectopic thyroid tissue could not be demonstrated, while the right lobe showed minimal hyperplasia. Without performing any invasive procedure, we enrolled the child in a follow-up program with the guidance of US and scintigraphy, which were effective both in making the final diagnosis of thyroid hemiagenesis and in evaluating the current status of the present thyroid tissue. In conclusion, if only one thyroid lobe is detected in a pediatric case initially with US or scintigraphy, the diagnosis of thyroid hemiagenesis should be suggested and, before any unnecessary or invasive attempt, the other complementary method (scintigraphy/US) should be performed.

Background. Thyroid carcinoma complicated by hemiagenesis is very rare, and previous reports have not described this cancer on the side of the absent lobe. Methods and Results. We report the case of a 64-year-old woman in whom left thyroid hemiagenesis was discovered incidentally during investigations of abnormal sensation during swallowing. A tumorous 1.4 cm lesion was also found on the side of the absent lobe, left of the isthmus. Fine-needle aspiration biopsy revealed class V papillary carcinoma, but no lymph node metastases. Total thyroidectomy was performed for stage cT1bN0M0 carcinoma. Histopathology revealed normal thyroid tissues in the right lobe and isthmus, while the left lobe was absent. The mostly papillary carcinoma was adjacent to the truncated thyroid tissue, with a portion histologically consistent with poorly differentiated carcinoma. Conclusions. All previously reported cases of thyroid cancer complicated by hemiagenesis have represented carcinoma occurring within the present lobe. This case is extremely rare.

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 lobe and absence of the left lobe. Nuclear scan, confirming absence of the left lobe, showed hot nodules in the right one. The diagnosis was toxic multinodular goitre.Case Two. The thyroid was not palpable in this patient presented with signs and symptoms of thyrotoxicosis. Biochemical analysis revealed the diagnosis of autoimmune thyrotoxicosis. Ultrasound showed mild diffuse hyperplasia of the right lobe and agenesis of the left lobe. Nuclear scan, confirming absence of the left lobe, showed increasing diffuse uptake of radiotracer in the right one. The diagnosis was Graves’ disease in this patient. After antithyroid medication, the patients were surgically treated with total excision of the thyroid tissue. TH is sometimes associated with disorders of the thyroid. Hyperthyroidism makes TH cases symptomatic. During evaluation of patients, ultrasound and nuclear scan usually report agenesis of one lobe and establish the diagnosis of TH. The surgical treatment is total removal of hyperactive tissue and total excision of the remaining lobe.

Abstract Background Thyroid hemiagenesis is a rare congenital anomaly in which one lobe of the thyroid gland fails to develop. There is an increased incidence of associated thyroid disorders in patients with thyroid hemiagenesis. Case presentation A 32-year-old Ugandan woman presented with a complaint of painless neck swelling of 3-months duration. The swelling was associated with a globus sensation. There was no history of thyroid – related problems or treatment prior to this presentation. Physical examination demonstrated a mobile right thyroid swelling without an obvious nodular contour. Neck ultrasound showed an absent left lobe of thyroid gland, a right lobe with a solitary nodule scoring two points on the Thyroid Imaging, Reporting and Data System (TI-RADS) and an isthmus in situ. Extensive search for possible ectopic thyroid tissue was negative. She was biochemically euthyroid. The patient was counseled about thyroid hemiagenesis and was put on a regular follow up in the clinic for the TI-RADS 2 nodule. Conclusion Thyroid hemiagenesis is often associated with other thyroid disorders. Its diagnosis should prompt an active search for other associated morphological or functional thyroid abnormalities.

1. In a series of rabbits the changes which took place in the histology of the left lobe of the thyroid gland after excision of the right lobe have been studied at varied intervals of time. 2 days after the removal of one lobe the other lobe showed a slightly increased colloid content, an increased vacuolation of the colloid, and a slight increase in the size of the epithelial cells. At the end of a week the vesicles were greatly increased in size, distended with colloid, and the epithelial cells were flattened, while after 3 to 4 months signs of compensatory hypertrophy were present. 2. The changes observed were uninfluenced by division of the vagus or cervical sympathetic.

AbstractObjective:We report an extremely rare case of thyroid hemiagenesis with ectopic lingual thyroid.Method:Case report and review of the world literature concerning thyroid hemiagenesis with ectopic lingual thyroid and heredity.Results:Ectopic thyroid is an uncommon embryological aberration characterised by the presence of thyroid tissue in a site other than its usual, pretracheal location. The lingual thyroid is the most common manifestation of benign ectopic thyroid tissue, but is still a rare clinical entity. Thyroid hemiagenesis is also a very rare abnormality, in which one thyroid lobe fails to develop. We report a case of left thyroid hemiagenesis and goitre in the right lobe in a 26-year-old woman with an ectopic lingual thyroid.Conclusion:To our knowledge, this is the first report in the world literature of thyroid hemiagenesis with ectopic lingual thyroid.

Abstract Objective: Incretins are expressed in thyroid tissue but without clearly-known clinical significance in human. The long-term effect of GLP-1 receptor activation on the thyroid is unknown. In the literature, liragludite-related thyroiditis has not been reported yet and here we wanted to draw attention to this association. Case Summary: A 52-year-old woman with type 2 diabetes mellitus presented with thyroid tenderness, tremor and fever. Her lab results were as follows: undetectable TSH, free T4 (FT4) = 2,4 ng/dl (0.93-1.7), free T3 (FT3) = 4.4 pg/mL (2-4.4). Erythrocyte sedimentation rate (ESR) was 60 mm/hour, C-reactive protein (CRP) was 80 mg/L. Thyroid autoantibodies were negative. USG revealed that thyroid gland was in normal localization and the right lobe was 24x22x46 mm and the left lobe was 20x21x45 mm, isthmus thickness was 5 mm. The parenchyma was heterogeneous, coarsely granular, with bilateral patchy hypoechoic areas. All these findings suggested that the patient had subacute thyroiditis. When we examine the etiological factors of subacute thyroiditis in the patient, there was no history of trauma, no previous viral or bacterial illness, contrast agent exposure. But, she had only been using liraglutide for a week. Firstly liraglutide therapy was ceased and than 20 mg prednisolone and 40 mg beta-blocker therapy was initiated. At the 8 weeks’ of cessation, patient had no symptoms. Also thyroid function tests and other laboratory values were all in normal limits. Conclusions: It has been proven by previous studies that liraglutide has several effects on the thyroid gland. Liraglutide therapy might be related to subacute thyroiditis, as well.

SummaryMorphological features of a normal thyroid gland in a geographical region where the daily iodine intake is about 1 mg are established. The mean weight of the thyroid gland is 31.3 gm with a range from 19 to 43 gm. Oblique length of the right lobe is 5.0 cm and that of the left lobe 4.8 cm. The surface area of the right and left lobes is 9.7 and 9.1 cm2, respectively. The weight of the thyroid gland calculated on the basis of the scan obtained with 99mTcO4 is quite variable and shows poor correlation (γ = 0.40) with the weight obtained on the basis of I-131 scan. It is suggested that the criteria of normalcy be established regionally based on iodine intake, and that an isotope of iodine be used in calculating the weight of thyroid gland for dosimetry purposes.

Thyroidal 99mTc uptake in the acute thyrotoxic phase of subacute thyroiditis (SAT) is always inhibited. However, a patient with SAT had signs in the right-side thyroid gland with transient thyrotoxicosis and slightly high 99mTc uptake levels in the right lobe, low 99mTc uptake in the left lobe, and normal overall uptake. Histological examination showed cellular destruction and granulomatous inflammatory changes in the right lobe, with marked interstitial fibrosis in the left lobe. The patient was thyrotrophin-receptor antibody (TRAb) positive. After a short course of prednisolone, SAT-like symptoms and signs improved. TRAb-positivity resolved spontaneously after 22 months, and TSH levels were slightly low for 22 months. Levels then kept normal in the following four years. In conclusion, high 99mTc uptake by the right lobe was due to the combined effects of TRAb and left thyroid gland fibrosis.

Abstract Background: Primary Thyroid Lymphoma is rare accounting for 2-5% of all thyroid malignancies and less than 2% of extranodal lymphomas. Data has suggested annual incidence to be 2 per 1 million. (1) Clinical Case: A 72-year-old female with coronary artery disease, hyperlipidemia and hypothyroidism was diagnosed with extranodal follicular cell lymphoma of the breast. FDG-PET showed evidence of diffuse avidity within her thyroid gland, with SUV of 13.8. She denied any drastic change in the size of her neck or any compressive symptoms. Thyroid ultrasound performed months before her diagnosis of lymphoma, showed a two-fold increase, most notable to the right lobe compared to prior imaging; her gland remained otherwise unchanged with heterogenous echotexture. Fine needle aspiration and flow cytometry were obtained on thyroid tissue that showed follicular cell lymphoma. She was started on single-therapy Rituxan regimen with oncology. Several months later appearance and examination of her neck had improved with decrease in size of thyroid gland. Repeat FDG-PET scans, with the most recent being 11 months after starting Rituxan therapy, showed reduction in the avidity within the thyroid gland and decreasing size; with SUV of 7.8. Repeat thyroid ultrasound continued to show heterogeneous echotexture with overall decrease in volume in gland size by nearly 50% within the right lobe and approximately 30% within the left lobe. Conclusion: Thyroid lymphoma should be suspected in a rapidly enlarging thyroid gland with or without pain or compressive symptoms. However, we propose that it should also be considered in the setting of FDG-PET avidity in thyroid tissue in setting of clinical suspicion. Diffuse FDG-PET scan avidity in the thyroid gland does not automatically equate to malignancy as prospective and retrospective information has shown that diffuse uptake can be seen incidentally, in cases of diffuse goiter, Graves disease or chronic lymphocytic thyroiditis and that the uptake has been seen to range between 5.6-16.8 SUV. (2) The American Thyroid Association 2015 thyroid cancer guidelines propose that if diffuse uptake is seen within the thyroid gland on PET imaging that thyroid ultrasound imaging and functional testing be undertaken. If imaging shows findings suggestive of only chronic lymphocytic thyroiditis (diffuse heterogeneous gland) that no further action is required. In this patient a different approach was taken with investigations pursued in the setting of enlarging thyroid gland on imaging and known extranodal lymphoma allowing for ultimate diagnosis.

Thyroid hemiagenesis is a rare form of thyroid dysgenesis characterized by an absence of half of the thyroid gland. Developmental hemi-thyroid anomalies can result from either an abnormal descent or an agenesis of one lobe of the thyroid gland. We report a case of a 40-year-old woman with history of a longstanding gradually progressive thyroid swelling without any complication. An ultrasonographic examination diagnosed the absence of the left thyroid lobe and enlargement of the right lobe, which was confirmed on a computed tomography (CT) angiogram and a radionuclide scan of the neck. A cytological examination showed nodular goiter with cystic degeneration. Right subtotal thyroidectomy was performed and histopathological examination confirmed adenomatous goiter with degenerative changes. We report the rarity of the condition and emphasize the role of a comprehensive radiological, cytological, and radionuclide algorithm for an accurate preoperative diagnosis and subsequent management.
