A 32-year-old woman was admitted to our hospital because of fever and back pain. Two months previously, she had been given a diagnosis of bacterial pneumonia based on the same symptoms and recovered after antibiotic treatment. Chest CT scans on admission showed a consolidation and thickened pleura in the right lower lobe. Bronchoalveolar lavage fluids showed an alveolar hemorrhage. Lung biopsy specimens showed thickened pulmonary arteries and fibrotic nonspecific interstitial pneumonia (NSIP). Three years later, she was admitted with fever and pain of the left arm and aortitis syndrome was diagnosed. In this case of NSIP pattern associated with aortitis syndrome we speculate that repeated pulmonary infarction and alveolar hemorrhages caused the NSIP pattern.
