BACKGROUND
Pycnodysostosis is typically associated with short stature, multiple fractures without adequate trauma and high bone density on x-ray. The increased bone density is due to a genetic defect of cathepsin K, leading to dysfunctional osteoclastic bone resorption and bone remodeling. We wanted
Despite advances in nuclear medicine, bone scintigraphy remains an important imaging technique. It is sensitive in detecting stress fractures and bone metastases and can assess suspected injury that is difficult to see on plain films (e.g., rib fracture). Scintigraphy is useful in evaluating new
In 2003, we reported on a 12-yr-old boy who had developed osteopetrosis (OPT) while receiving pamidronate (PMD) for idiopathic bone pain and enigmatic elevation in circulating bone alkaline phosphatase. Now 17 yr of age, he was re-evaluated 6.5 yr after PMD exposure stopped. Our patient described
