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:
