Fleischner Society Guideline Update 2017: Management of Solid Pulmonary Nodules.
Updated 2017 Fleischner Society guidelines advise a less intensive approach to the management of most small pulmonary nodules incidentally discovered on CT scans. The Fleischner Society now recommends that solid nodules 6 mm or less in diameter in low-risk adults >35 years old generally need no further follow-up.
In higher-risk patients, a follow-up CT scan should be considered optional. The recommendations apply even if multiple solid pulmonary nodules ≤6 mm are present.
