Thyroid hemiagenesis resulting from the failure of embryologic development of one thyroidal lobe is a very rare anomaly. It is usually incidentally discovered during the investigation of accompanying thyroid disorders. Here we report three cases with right lobe agenesis in two patients and left lobe agenesis in one patient. Two of them were hyperthyroid, while the other euthyroid patient had a ...

OBJECTIVE Thyroid hemiagenesis is a rare congenital disorder characterized by the absence of a lobe and/or of isthmus. Studies on the association between thyroid hemiagenesis, Graves' disease and differentiated thyroid cancer are rare. CASE PRESENTATION We describe the medical and surgical history of a patient in whom a molecular evaluation was performed. A 36-year-old man presented with symp...

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 o...

Introduction: This study deals with the histo-morphometric study of human thyroid glands, with emphasis on pyramidal lobe. Materials & Methods : 102 formalin preserved cadavers were dissected and Thyroid Glands (65 male and 37 female) were studied. The specimens were studied for the extent and dimensions of lobes, isthmus and the number, extent and attachment of both the PL and levator glandula...

In this article, we report a very rare case of left thyroid lobe with agenesis, adenomatous hyperplasia and coexisting papillary carcinoma of the right lobe. A 59-year-old asymptomatic woman with no previous thyroid surgery was evaluated sonographically. Ultrasonography and scintigraphy revealed an agenesis in the left lobe and multiple right lobe nodules with one of them diagnosed with papilla...

Although the pathological relationship between parathyroid and thyroid diseases is common, an association between parathyroid adenoma and thyroid cancer is rare. Concomitant thyroid cancer in patients with primary hyperparathyroidism (pHPT) has been reported at varying frequencies. WE present here a 23-year-old man who had papillary thyroid carcinoma in the right thyroid lobe and a parathyroid ...

The size and shape of the thyroid gland is subject to much variation, as stated by Wood Jones. Literature is replete with a large number of variations of the gland. By utilizing various techniques like gross dissection, histology, developmental anatomy, and recently thyroid scans and scintigraphy, some common and certain rare anomalies of the thyroid with their possible developmental bases are ...

OBJECTIVE The aim of this study is to investigate the presence of pyramidal lobe in thyroid scintigraphy and to compare the presence of pyramidal lobe in different thyroid pathologies between genders. METHODS Images of 866 patients (663 female, 203 male) with ages ranging from 8 to 85 were evaluated retrospectively. Presence of pyramidal lobe and its location were established in images. Patie...

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...
