title: Pulmonary amyloidosis with calcified nodules and masses - a six-year computed tomography follow-up: a case report.
abstract: BACKGROUND
  Pulmonary amyloidosis is an uncommon disease, characterized by extracellular deposition of fibrillary protein in the lungs. It appears in three forms: tracheobronchial, nodular pulmonary, and alveolar septal. There are few reports of long-term observation of primary pulmonary amyloidosis.
  
  
  METHODS
  We present the case of a 47-year-old man who presented with fever, dyspnea, cough and hemoptysis. Chest radiograph and computed tomography revealed multiple pulmonary nodules and masses. The patient underwent open lung biopsy, which diagnosed pulmonary amyloidosis.
  
  
  CONCLUSIONS
  Pulmonary nodular amyloidosis should be considered in the differential diagnosis of pulmonary nodules or masses.
