This replaces the term bronchoalveolar carcinoma and introduces the concept of preinvasive, minimally invasive, and frankly invasive lesions to the classification. Although more work is required to validate these concepts, it is likely that they will be incorporated into the next World Health Organization and TNM classifications. We illustrate the likely radiographic appearance of lesions in the new classification, highlight salient features to watch for on follow-up, and offer guidance on their management.
