title: A rare case of multinodular pulmonary amyloidosis.
abstract: OBJECTIVE
  Pulmonary amyloidosis is usually associated with systemic amyloidosis. Localized pulmonary amyloidosis without systemic amyloidosis is even rare. We reported a rare case of multinodular pulmonary amyloidosis to improve the understanding of the disease.
  
  
  METHODS
  Report of a case.
  
  
  RESULTS
  We present an unusual case of primary pulmonary multinodular amyloidosis in a middle-aged woman. She presented our hospital with cough and chest distress only. Results of computed tomography (CT) showed multiple nodules with diffused calcification and thick-walled cavity in bilateral lung parenchyma. And the diagnosis of nodular amyloidosis was established by a CT-guided core needle biopsy.
  
  
  CONCLUSIONS
  The case clearly shows it is difficult to distinguish parenchymal nodular amyloidosis from malignant primary lung neoplasm in radiology because of their similar images. Thus, the role of CT-guided core needle biopsy in diagnosis of pulmonary multinodular amyloidosis is very important.
