“…Ultrasound is also recommended as an excellent mode for evaluating the thyroid gland because it directly visualizes the thyroid tissue and readily determines its presence or absence. 9 The most commonly associated entity with hemiagenesis is hyperthyroidism including Graves' disease, toxic autonomously functioning thyroid adenoma, and toxic multinodular goiter, s,~° There has only been on° previously reported case associated with chronic thyroiditis. Additionally, there have been single case reports of primary hypothyroidism, secondary hypothyroidism, and hyperparathyroidism.…”

“…Scintigraphy with 99m Tc-pertechnetate or 123 I can give proof of THA ( Fig. 1) and is helpful for detecting ectopic thyroid tissue [2,45,46]. After diagnosis of THA, scintigraphy can also be used to diagnose thyroid pathologies in the remaining lobe associated with hyperthyroidism (thyroid adenoma, Graves disease) or growing thyroid nodules with suspicion of malignancy [2,46].…”

Summary Hemiagenesis of the thyroid gland (THA) represents a rare congenital anomaly. It is characterized by the absence of one thyroid lobe, and sometimes the isthmus as well. It can occur with all kinds of other thyroid pathologies that may be present in the remaining thyroid lobe. A case of a 21-year-old male patient is presented; he sought a thyroid consultation because of hair loss, fatigue, and problems concentrating, thus raising the suspicion of hypothyroidism. Thyroid function was normal, but sonography of the thyroid gland revealed THA of the left lobe and the isthmus. The current knowledge concerning the genesis and the clinical consequences of THA are discussed based on the current literature.

“…1,2 The left side is the most commonly involved in hemiagenesis (80%). [3][4][5] Clinically, these patients may be euthyroid, hyperthyroid, or hypothyroid. [3][4][5] The isthmus may be absent in 40.50% of cases.…”

“…[3][4][5] The isthmus may be absent in 40.50% of cases. [3][4][5] Thyroid function may be altered in 38.47% of patients. [3][4][5] Recognition of this rare anomaly by means of ultrasonography is valuable for a complete thyroidectomy and for avoiding unnecessary contralateral dissection and damage.…”

Background/objectives: As congenital anomalies of the thyroid are rare and the pathology associated with it warranting total thyroidectomies is still rare, so the inadvertent parathyroidectomies are rarely reported. Unilateral or bilateral hypoplasia or agenesis of one or both thyroid lobes, with or without isthmic agenesis, is a rare developmental anomaly. Meticulous subcapsular dissection with preserving the vascular twigs to the parathyroid is very important in avoiding complications. Materials and methods:We report two cases of thyroid hemiagenesis in our medical college institution over a period of 10 years. Both were females in the 6th decade with swelling in the neck. One had a right-sided swelling and the second had a left-sided swelling, both measuring about 5 × 5 cm.Conclusion: So the total thyroidectomy surgery in hemiagenesis cases poses a risk to the parathyroids as the altered anatomy. So the time-tested technique of subcapsular dissection and meticulous preservation of the multiple vasculature of the parathyroids in the fascial compartment provides better results with least morbidity.
