Pulmonary Curriculum: Interstitial Lung Disease

interstitial lung disease

  1. List and identify on a chest radiograph and chest CT four patterns (nodular, reticular, reticulonodular, and linear) of interstitial lung disease (ILD).
    • Answer
  2. Make a specific diagnosis of ILD when supportive findings are present in the history or on radiologic imaging (eg, dilated esophagus and ILD in scleroderma, enlarged heart and a pacemaker or defibrillator in a patient with prior sternotomy and ILD secondary to amiodarone drug toxicity).
  3. Identify Kerley A and B lines on a chest radiograph and explain their etiology.
  4. Recognize the changes of congestive heart failure on a chest radiograph—enlarged cardiac silhouette, pleural effusions, vascular redistribution, interstitial or alveolar edema, Kerley lines, enlargedazygos vein, increased ratio of artery to bronchus diameter.
  5. Define the terms “asbestos-related pleural disease” and “asbestosis”; identify each on a chest radiograph and chest CT.
  6. Describe what a “B” reader is as related to the evaluation of pneumoconioses.
  7. Identify honeycombing on a radiograph and chest CT, state the significance of this finding (end-stage lung disease), and list the common causes of honeycomb lung.
  8. Describe the radiographic classification of sarcoidosis.
  9. Recognize progressive massive fibrosis/conglomerate masses secondary to silicosis or coal worker’s pneumoconiosis on radiography and chest CT.
  10. Recognize the typical appearance and upper lobe predominant distribution of irregular lung cysts or nodules on chest CT of a patient with Langerhans cell histiocytosis.
  11. List four causes of unilateral ILD.
  12. List three causes of lower lobe predominant ILD.
  13. List two causes of upper lobe predominant ILD.
  14. Identify a secondary pulmonary lobule on CT.
  15. Recognize findings of lymphangioleiomyomatosis on a chest radiograph and CT.
  16. Identify and give appropriate differential diagnoses when the patterns of septal thickening, perilymphatic nodules, bronchiolar opacities (“tree-in-bud”), air trapping, cysts, and ground glass opacities are seen on CT.
