Overview

On chest X-ray, characteristic findings of non-small cell lung cancer include rounded or spiculated mass, bulky hilum (representing the tumor and local nodal involvement) and lobar collapse.

Chest X Ray

  • Conventional chest radiograph may be helpful in the diagnosis of non-small cell lung cancer.[1][2]
    • The majority of non-small cell lung cancers require further evaluation with either CT scan or MRI
    • Chest X-ray helps to assess the involvelment of lung and adjacent structures:
  • On conventional radiography, characteristic findings of non-small cell lung cancer include:[2]
  • Rounded or spiculated mass
  • Bulky hilum (representing the tumor and local nodal involvement)
  • Lobar collapse
  • Cavitation may be seen as an air-fluid level
  • Pleural effusion
  • On conventional radiography, signs of non-small cell lung cancer include:[2]
  • Golden "S" sign: created by a central mass obstructing the upper lobe bronchus and should raise suspicion of a primary lung cancer. Usually seen with right upper lobe collapse.
  • Coin lesion: round or oval, well-circumscribed lesion
  • Luftsichel sign: curvilinear opacity represents compensatory hyperinflation of the lobe
  • Bronchial cut off sign: abrupt truncation of a bronchus from obstruction
