Cystic parathyroid adenoma is one of rare causes of hyperparathyroidism, and tends to cause increased serum level of parathyroid hormone, alkaline phosphate and serum calcium level similar to when compared to those of solid adenoma. The possibility of a coincidental appearance of primary hyperparathyrodism and nonmedullary thyroid cancer is rare, and often neglected. A 40-year-old female presented with constipation and weight loss for 3 months. The serum calcium, phosphate and alkaline phosphate were 16.6 mg/dl, 2.2 mg/dl and 505 IU/L respectively and serum parathyroid hormone level was 1556.2 pg/mL. Neck US showed mixed nodules at both thyroid lobes, and PET-CT showed a right thyroid nodule without FDG uptake. The patient was diagnosed of primary hyperparathyroidism and underwent parathyroidectomy and a total thyroidectomy. Histopathologic results revealed parathyroid adenoma with cystic change (2 cm greater diameter) in the right lower parathyroid gland and coexistent papillary carcinoma of the right lobe of thyroid gland (infiltrating, 0.3 cm in greater diameter). She remained well and serum calcium, phosphate, parathyroid hormone level were normalized within 24 hours.

$^{201}Tl-^{99m}Tc$ 감영스캔이 시행되었던 65명의 환자에서 $^{201}Tl-^{99m}Tc$ 감영스캔의 진단적 가치와 위 음성과 위 양성의 원인에 대해 조사하였다. 이들 중 21예가 부갑상선선종으로 확진되었고, 이들에서 $^{201}Tl-^{99m}Tc$ 감영스캔의 예민도는 90.5%, 특이도는 97.6%였다. 위 음성을 보인 예는 낭종성 괴사를 보인 부갑상선선종과 크기가 $1.5{\times}1{\times}0.8 cm$ 정도로 작은 종양이었다. 위 양성을 보인 1예는 무 기능성 갑상선종이었다. 결론적으로 $^{201}Tl-^{99m}Tc$ 감영스캔은 부갑상선 종괴를 찾아내는데 특이도와 예민도가 높은 검사로 생각된다.
