Overview
On conventional radiography, 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.[1]
X Ray
- Conventional chest radiograph may be helpful in the diagnosis of non-small cell lung cancer
- The majority of non-small cell lung cancers require further evaluation with CT scan and MRI
- Common features of conventional radiography to perform the diagnosis of non-small cell lung cancer, 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
- Detection of pleural effusion
- 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
Gallery
-
Golden "S" Sign (or reverse "S" sign of Golden) : right upper lobar collapse (the right upper lobe appearing dense and shifting medially and upwards, with a central mass expanding the hilum -
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 -
Malignant pleural effusion
