A 35-year-old male patient with generalized body pain had multiple hyperactive lesions on bone scan, suggestive of metastatic disease. FDG PET/CT scan performed 2 weeks later showed multiple hypermetabolic lesions on skeletal system; also a hypermetabolic and hypodense lesion was present adjacent to the left thyroid lobe, suggestive of primary parathyroid adenoma and multiple brown tumors. Serum parathyroid hormone level was elevated, and parathyroid scintigraphy confirmed parathyroid adenoma. The patient underwent parathyroidectomy operation, and histopathology result revealed parathyroid adenoma. Five months after the operation, complete metabolic regression was observed on PET/CT, whereas bone scan did not show any significant difference.
