Insights
This case study describes hemiagenesis of the left thyroid lobe, a rare condition. The patient also had chronic lymphocytic thyroiditis, an association not previously documented in medical literature.
Area of Science:
- Endocrinology
- Radiology
- Pathology
Background:
- Thyroid hemiagenesis is a rare congenital anomaly where one lobe of the thyroid gland fails to develop.
- Hypothyroidism is a common endocrine disorder, often associated with autoimmune conditions like thyroiditis.
Observation:
- A patient presented with clinical hypothyroidism and a right-sided goiter.
- Imaging studies, including Tc-99m pertechnetate scan and ultrasonography, indicated hemiagenesis of the left thyroid lobe.
- Fine-needle aspiration cytology revealed chronic lymphocytic thyroiditis in the right thyroid lobe.
Findings:
- The case demonstrates hemiagenesis of the left thyroid lobe.
- Chronic lymphocytic thyroiditis was diagnosed in the contralateral right lobe.
- This represents a potentially novel association between thyroid hemiagenesis and chronic lymphocytic thyroiditis.
Implications:
- This case highlights the importance of comprehensive evaluation in patients with thyroid anomalies.
- Understanding this association may improve diagnostic and management strategies for similar rare thyroid conditions.
- Further research is warranted to explore the potential link between congenital thyroid malformations and autoimmune thyroid disease.
Abstract:
The authors report a case of hemiagenesis of the left thyroid lobe indicated on Tc-99m pertechnetate scan and later confirmed on ultrasonography. The patient was clinically hypothyroid with a right-sided goiter. The cytopathologic diagnosis was made by fine-needle aspiration cytologic analysis, which indicated chronic lymphocytic thyroiditis in the right lobe of the thyroid gland. Later the patient's condition was stabilized with thyroxine replacement therapy. The association of hemiagenesis of the thyroid with chronic lymphocytic thyroiditis has not been reported in the literature.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
