• Four items on initial evaluation of patient that indicate new diagnosis of ILD
  • Subacute presentation
  • Hypoxemia/impaired A-a gradient

• Four categories of Interstitial Lung Disease
  • Rare - LAM, eosinophilic granuloma
  • Known causes - Occupational exposures, environmental exposures, connective tissue diseases
  • Granulomatous disease - sarcoidosis, hypersensitivity pneumonitis
  • Idiopathic interstitial pneumonas

• Idiopathic Interstitial Pneumonias
  • Acute interstitial PNA (AIP) - acute (presentation of one month or less), idiopathic ARDS, very rare
  • Respiratory bronchiolitis-ILD (RB-ILD), desquamative interstitial PNA (DIP) - smoking-related
  • Cryptogenic organizing PNA (COP) - alveolar-filling process, mass-like and nodular in appearance
  • Non-specific interstitial PNA (NSIP) - basilar-predominant process, ground glass opacities and reticular pattern on imaging, 80% of patients will have fibrotic pattern as well, seen in patients with undifferentiated connective tissue disease, SLE, Sjogren's, Systemic sclerosis, and dermatomyositis
  • Usual interstitial PNA/Idiopathic pulmonary fibrosis (UIP/IPF) - basilar predominance, honey-combing pattern, seen in patients with RA
