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
- Findings on CT scan suggestive of adenocarcinoma of the lung include:[1]
- 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.
- Histologically, the ground-glass attenuation corresponds to a lepidic growth pattern and the solid component corresponds to invasive patterns.
- Hence, the preinvasive category of adenocarcinoma in situ, minimally invasive adenocarcinoma, and lepidic predominant invasive adenocarcinoma is often seen as ground glass nodule or sub-solid nodule with a predominant ground-glass component.
- On the other hand, the remaining invasive subtypes of adenocarcinoma is usually a solid nodule but may also subsolid and only occasionally seen as ground glass nodule.
- Invasive mucinous adenocarcinoma subtype may have a variable appearance ranging from consolidation, air bronchograms or seen as multifocal subsolid nodules or masses.
