Primary and secondary hyperparathyroidism: Findings on chest X-rays and high resolution CT

Hyperparathyroidism induces high level of serum calcium, with mobilization from bone. Consequence of this process is the deposition in the soft tissue. In the lung deposition of calcium induces restrictive changes with hypoxemia. Two different cases of hyperparathyroidism are shown in this report in which high level of calcium has induced early and late parenchymal changes.
