Diffuse Lung Diseases – High Yield Facts

  • Thickened intralobular lines MC seen in idiopathic pulmonary fibrosis (IPF).

  • Thin-walled cysts – LAM, eosinophilic granulomatosis
  • UIP & sarcoidosis r d MC causes of irregular lung interfaces.
  • GGO defined as an area of increased attenuation on HRCT within which normal parenchymal structures r visible. Produced by thickening of alveolar septa by inflammatory exudate. Seen in DIP, PCP, NSIP, AHP, IPE. Often implies an active inflammatory process that is reversible.
  • Sarcoidosis & UIP r d diseases MC asso with architectural distortion.
  • Traction bronchiectasis MC in UIP & fibrotic sarcoidosis.
  • Conglomerate masses – End stage sarcoidosis
