PTH and hyperparathyroidism: Wadhawan et al reported in their case study that the PTH levels of the patient plummeted after undergoing parathyroidectomy and the brown tumor also reduced by a considerable amount which strikingly contrasts with our case in which the labs showed persistently raised PTH and low calcium and normal phosphorus highlighting the fact that even parathyroidectomy may not be adequate sometimes for the treatment of hyperparathyroidism.[1]
