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.[1]
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:[2]
- Primary detection and characterization of parenchymal tumor
- Assessment of main bronchi and tracheal involvement
- Detection of chest wall invasion
- Assessment of hiliar and mediastinal invasion/adenopathy
- Detection of obstructive atelectasias and signs of pneumonitis
- On conventional radiography, characteristic findings of squamous cell carcinoma of the lung, 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
- On conventional radiography, signs of squamous cell carcinoma of the lung, 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

Squameous cell lung cancer: lung cavitating mass left upper lobe adjacent to the oblique fissure. The prominent air-fluid level is best seen on the lateral radiograph
-
Luftsichel sign: curvilinear opacity at the left apex represents compensatory hyperinflation of the left lower lobe
-
Coin lesion sign: round or oval, well-circumscribed lesion, compatible with primary lung cancer
-
Bronchial cut off sign: abrupt truncation of a bronchus from obstruction
