Abstract:
We present a 54-year-old woman with chronic kidney disease, hypercalcemia, and hyperparathyroidism, who exhibited multiple osteolytic lesions and a suspicious parathyroid adenoma. 18 F-FDG PET/CT revealed increased metabolic activity in the lytic lesions, raising suspicion for multiple myeloma or brown tumors. A biopsy confirmed brown tumors. Subsequent 68 Ga-Trivehexin PET/CT showed intense αvβ6-integrin expression in the parathyroid adenoma and moderate uptake in the brown tumors. This highlights the potential utility of 68 Ga-Trivehexin in the characterization of osteolytic lesions in hyperparathyroidism.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
