Abstract

|
|
|
Thyroid hemiagenesis is a rare anomaly, which is the result of failure of embryologic development of a lobe of thyroid gland. It is more frequently found in the left lobe and in female patients. We, herein, report an extremely rare case of thyroid hemiagenesis associated with papillary thyroid carcinoma. A 69-year-old female presented with an incidentally discovered thyroid nodule in the right thyroid during a routine medical check-up. Ultrasonography(US) and computed tomography(CT) disclosed 0.7{times}0.5cm;and;2.8{times}2.2cm sized nodules in the right thyroid. The left thyroid, however, was not seen in the imaging studies of US and CT. Fine-needle aspiration of the small and large nodules showed papillary thyroid carcinoma and adenomatous hyperplasia, respectively. The patient underwent a right total thyroidectomy with central compartment node dissection. The operative findings and histologic examination confirmed the absence of the left thyroid associated with papillary thyroid carcinoma and ademonatous hyperplasia of the right thyroid.
