Signs and Findings in Interstitial Disease

  • Air Trapping

    • Video

    • Mosaic attenuation
      Small Airways are obstructed and air is trapped Sometimes small vessel disease, as in vasculltis, can lead to the air trapping

  • Consolidation

    • FOCAL CONSOLIDATION IN ILD
      Focal consolidations or infiltrates are another feature of interstitial lung disease (yellow ring with obscuration of the airways and vessels Courtesy You Tube on ILD

  • Crazy Paving

  • CRAZY PAVING IN ILD
    Crazy paving in ILD is another another CT feature of interstitial lung disease and is characterised by diffuse ground glass caused by a combination of interlobular septal and intralobular septal thickening resulting well demarcated patchy densities in the lungs. Courtesy You Tube on ILD

  • Honeycomb Change

    • HONEYCOMB CHANGES IN ILD
      Honeycomb changes in ILD is a feature on CT of interstitial lung disease and is characterised by clusters of stacked cystic air spaces in the periphery and predominantly posteriorly at the bases of the lungs . They likely represent small airways that have been denuded of the their alveoli apparatus. It is most commonly associated with idiopathic pulmonary fibrosis (IPF) and its radiological equivalent UIP – usual interstitial pneumonia. You Tube on ILD

      NODULES IN ILD
      Micronodules in ILD is another another CT feature of interstitial lung disease and is characterised by nodules of a variety of shapes and sizes and likely centrilobular in origin. Sometimes they are ill defined such as in this case. You Tube on ILD

  • Traction Bronchiectasis

    • Video
    • TRACTION BRONCHIECTASIS IN ILD
      Traction bronchiectasis and bronchiolectasis (yellow ring) is as a result of fibrotic traction on the airways. You Tube on ILD

Coronal CT shows symmetrical bibasilar reticular change, bronchovascular thickening , ground glass changes and subpleural sparing, all features characteristic of NSIP
