Imaging findings
A radiograph showed a large extrapleural sign on the right, initially mistaken for a pulmonary abnormality, and a smaller similar lesion expansile from a rib. The spine showed a classic rugger jersey appearance. Imaging showed multiple osteoclastomas in the ribs and pelvis.
Key takeaways
The patient had chronic renal failure and secondary hyperparathyroidism, which caused multiple brown tumors (osteoclastomas) and the characteristic rugger jersey spine. Erosion of the distal clavicle was also noted, a good place to look for signs of hyperparathyroidism.
