Overview
CT Scan
Sometimes it is impossible to radiographically distinguish between other histological lung cancer types.
A lung nodule is a rounded or irregular region of increased attenuation measuring less than 3 cm. The amount of attenuation can further classify the nodules as either ground glass, sub-solid or solid.
Histologically, the ground-glass attenuation corresponds to a lepidic growth pattern and the solid component correspond to invasive patterns. Hence the preinvasive category of AIS, MIA, and the invasive subtype of LPA 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 (formerly mucinous BAC) can have a variable appearance ranging from consolidation, air bronchograms or seen as multifocal subsolid nodules or masses.
