New criteria for atypical pulmonary cysts and cavitary nodules

The Lung RADS 2022 update introduces new criteria for classifying and managing atypical pulmonary cysts and cavitary nodules. Atypical pulmonary cysts, often under-recognized, can be categorized between Lung RADS 3 and 4B based on features like thick or asymmetric walls, associated nodules, internal septations, or growth. Cavitary nodules are managed based on the dominant feature, treated as solid Cavitary Nodules if the solid component is dominant and as atypical lung cysts if the cystic component is more prominent. In case of suspicion of infection, Cavitary Nodules are placed in category zero, requiring follow-up CT scans. These additions improve the understanding and management of these nodules.
