Overview
An x-ray may be helpful in the diagnosis of lung mass. Findings on an x-ray suggestive of lung mass include rounded or spiculated mass, bulky hilum, and lobar collapse.
X Ray
An x-ray may be helpful in the diagnosis of lung mass. On an x-ray, lung mass may appear as hyperdense pulmonary mass or cavitating pulmonary mass. The 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
