Figure 1 Radiologic appearance of myositis-related interstitial lung disease (ILD). A, Nonspecific interstitial pneumonia (NSIP) pattern. High-resolution CT (HRCT) scan demonstrating the characteristic radiographic appearance of NSIP with peripheral ground glass and irregular reticulation with subpleural sparing. B, Organizing pneumonia (OP). HRCT scan demonstrating the characteristic radiographic appearance of OP with rounded regions of peribronchovascular and subpleural consolidation. C, Combination of NSIP and OP pattern. HRCT scan demonstrating peripheral ground glass and peripheral consolidation.

Figure 2 Histopathologic appearance of myositis-related interstitial lung disease (ILD). A, Fibrosing and cellular nonspecific interstitial pneumonia (NSIP) pattern. Lung biopsy specimen demonstrates uniform thickening of the alveolar septa by fibrosis and chronic inflammation. B, Organizing pneumonia (OP). A lung biopsy specimen demonstrating polypoid rounded plugs of granulation tissue are noted within alveolar spaces.

Figure 3 Proposed algorithm for the treatment of myositis-related interstitial lung disease (ILD). AZA = azathioprine; CsA = cyclosporine A; CYC = cyclophosphamide; HRCT = high-resolution CT; IVIG = IV immunoglobulin; MMF = mycophenolate mofetil; PFTs = pulmonary function tests.
