ABSTRACT
Tuberculosis of the thyroid gland is rare, and tuberculous granulomatous inflammation of the parathyroid glands is even rarer. The present study reports a rare case of primary hyperparathyroidism caused by tuberculous granulomatous inflammation. A 58-year-old female patient presented with generalized body pain persisting for 1 year. She had a history of recurrent renal stones (>20 times) and an incidental finding of multinodular goiter involving the parathyroid on neck ultrasound. A blood analysis revealed elevated levels of serum calcium (11.26 mg/dl) and parathyroid hormone (154.7 pg/ml). The patient underwent the resection of the affected left thyroid lobe under general anesthesia. A histopathological examination revealed parathyroid adenoma with caseating granulomatous inflammation involving the adenoma with focal lymphocytic thyroiditis of the left thyroid gland. Although granulomatous parathyroid disease with parathyroid adenoma causing hypercalcemia is an extremely rare event, it can occur. The treatment of choice is surgical resection.
