title: [Multiple bilateral pulmonary nodes following breast cancer].
abstract: METHODS
  Multiple new pulmonary nodules were demonstrated at chest radiography in a 69-year-old woman who had been treated for breast cancer ten years previously.
  
  
  METHODS
  Laboratory tests suggested mild inflammation. Pulmonary function tests demonstrated small airways disease. But because of an atypical morphology at computed tomography (CT), metastases were considered unlikely. CT-guided percutaneous biopsy revealed cryptogenic organizing pneumonia (COP).
  
  
  METHODS
  Oral medication with decreasing doses of steroids resulted in clinical and radiological improvement.
  
  
  CONCLUSIONS
  Even in a patient with known malignancy the differential diagnosis of multiple bilateral pulmonary nodules includes a variety of conditions and is meticulous, if necessary invasive diagnostic procedures are required.
