Squamous cell carcinoma of the lung chest x ray

Introduction

Overview

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
