Case Discussion

This patient had been treated for tuberculosis 25 years earlier.

Calcified intrapulmonary mass lesions are uncommon. The list of possible causes include:

  • prior exposure to silica dust
  • calcified metastatic deposits e.g. soft tissue and bone primary sarcomas
  • pulmonary amyloidosis
