Adenocarcinoma is the most common histologic type of lung cancer worldwide. A new classification of adenocarcinoma of the lung was published in 2011 by an international multidisciplinary committee sponsored by the International Association for the Study of Lung Cancer, the American Thoracic Society, and the European Respiratory Society. ). 43 This new classification has provided uniform terminology and the latest understanding of the various pathologic subtypes of adenocarcinoma of the lung. The majority of the pathologic subtypes of adenocarcinoma present as solid or subsolid (pure ground glass or part solid nodule) nodules on imaging. Radiologic presentations of various subtypes of adenocarcinoma show overlap. Invasive mucinous adenocarcinoma, previously called mucinous bronchoalveolar carcinoma, is the most common histologic subtype, which can present as a consolidation with air bronchogram on imaging. Invasive mucinous adenocarcinoma can have a wide spectrum of presentation on imaging ranging from subsolid nodules to solid nodules to consolidation. 44,45 Adenocarcinoma can be solitary or multifocal and can mimic pneumonia or organizing pneumonia radiologically ( Fig. 11

N2 - Airspace disease can be acute or chronic and commonly present as consolidation or ground-glass opacity on chest imaging. Consolidation or ground-glass opacity occurs when alveolar air is replaced by fluid, pus, blood, cells, or other material. Airspace disease is considered chronic when it persists beyond 4-6 weeks after treatment. These can be secondary to certain infectious, inflammatory, or neoplastic conditions. Computed tomography of the chest is usually performed in this set of patients to identify characteristic imaging findings. Familiarity with the differential diagnosis and characteristic imaging findings for chronic airspace disease is very important for guiding patient's management in a timely fashion.
