Overview
X ray
An x-ray may be helpful in the diagnosis of lung mass. Findings on an x-ray suggestive of lung mass include hyperdense pulmonary mass or cavitating pulmonary mass.
- On plain radiograph, characteristic findings of lung mass, include:[1]
- 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

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
-
Squamous 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
