Overview
CT scan is the method of choice for the evaluation of lung mass. On CT scan, characteristic findings of lung mass include single pulmonary nodule or mass with localized area of parenchymal consolidation and bubble-like areas of low attenuation within the lung mass (characteristic finding).
CT scan
CT scan is the method of choice for the evaluation of lung mass. The evaluation of lung mass will depend on several characteristics such as calcification, margins, location, distribution, and attenuation. On CT scan, characteristic findings of lung mass, include:
- Single pulmonary nodule or mass
- Localized area of parenchymal consolidation
- Bubble-like areas of low attenuation within the lung mass (characteristic finding)
- Hilar and mediastinal lymphadenopathy is uncommon
- Persistent peripheral consolidation

Bronchogenic lung carcinoma: upper lobe collapse

Bronchogenic lung carcinoma: upper lobe with lymphangitic spread
-
Adenocarcinoma of the lung: ground-glass attenuation corresponds to a lepidic growth pattern and the solid component correspond to invasive patterns.
-
Squamous cell lung carcinoma: Peripheral squamous cell lung carcinoma may be seen as a solid nodule/mass with or without an irregular border. The irregular margin can be attributed to a desmoplastic reaction or infiltrative growth
