Overview
Chest CT scan may be helpful in the diagnosis of adenocarcinoma of the lung. Finding on CT scan suggestive of adenocarcinoma of the lung is a lung nodule with a rounded or irregular region of increased attenuation.
CT Scan
- CT scan is the preferred modality for staging adenocarcinoma of the lung.
- Findings on CT scan suggestive of adenocarcinoma of the lung include:[1]
- Adenocarcinoma appears as a lung nodule with a rounded or irregular region of increased attenuation, measuring less than 3 cm.
- Based on degree of attenuation, lung nodules may be either ground glass, sub-solid, or solid.
- Ground-glass attenuation corresponds to a lepidic growth pattern.
- Solid component corresponds to invasive patterns.
- Preinvasive category of adenocarcinoma in situ, minimally invasive adenocarcinoma, and lepidic predominant invasive adenocarcinoma has mostly a ground-glass component.
- Invasive subtypes of adenocarcinoma are usually solid nodules.
- Invasive mucinous adenocarcinoma subtypes may have a variable appearance:
- Consolidation
- Air bronchograms
- Multifocal subsolid nodules or masses
