Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Shanshan Cen, M.D. [2] Maria Fernanda Villarreal, M.D. [3]

Overview

On chest X ray, characteristic findings of squamous cell carcinoma of the lung, 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 squamous cell carcinoma of the lung
  • The majority of squamous cell carcinomas of the lung require further evaluation with CT scan and MRI
  • Common features of conventional radiography to perform the diagnosis of squamous cell carcinoma of the lung, include:[1]


  • On conventional radiography, characteristic findings of squamous cell carcinoma of the lung, include:[1][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


  • On conventional radiography, signs of squamous cell carcinoma of the lung, include:[1]
  • 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
  • Golden "S" Sign (or reverse "S" sign of Golden) :Chest x-ray demonstrates increased density in the upper medial hemithorax with loss of volume, and shift of the trachea to the right. A mass is present at the right hilum. via, radiopedia.com Case courtesy of A.Prof Frank Gaillard[3]
