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.
Clarification on juxtapleural and airway nodules
Lung RADS 2022 clarifies the categorization of juxtapleural and airway nodules. Juxtapleural nodules, located along the costal, mediastinal, and diaphragmatic pleural surfaces, can be safely classified based on the criteria for perifigeral nodules. Airway nodules, previously termed endobronkyon nodules, are now classified into categories 0, 2, 4A, or 4B. Features like location, presence of air, and stability or growth on follow-up examinations determine their categorization. Clearer definitions and categorization prevent unnecessary follow-up and workup of benign nodules.
