We report the case of a 47-year-old woman, who had hemodialysis with secondary hyperparathyroidism and who developed progressive unbearable leg pain. Bone lesions suggestive of brown tumors were observed on initial x-ray examinations. This etiology was strengthened by PET/CT images showing F-18 FDG avid osteolytic lesions but no abnormal uptake suggestive of a primary neoplasm. The major metabolic regression of the lesions 6 months after total parathyroidectomy eventually confirmed the diagnosis. This case illustrates the potential usefulness of PET/CT in the noninvasive diagnosis and follow-up of brown tumors.
