Most occurred in the upper lobes(20/28), especially RUL(13/28). Mean age was 67.6+/-21 years. Mean smoking habit was 25 PY. Most patients had PS of 0-1 (91.3\%-21/23), were asymptomatic (78.3\%-18/23), had no cancer history (78.3\%-18/23). pGGN{\textquoteright}s: 75\% (21/28) of SSN{\textquoteright}s;mean diameter 11.5 mm, 15/21 had regular borders. PSN: 25\% (7/28) of SSN{\textquoteright}s; mean diameter 8.4 mm, 85.7\% had regular borders.Conclusions: Chest CT was the commonest imaging modality that identified SSN{\textquoteright}s incidentally. SSN patients with smoking histories had smaller nodules than life-long non-smokers which will need to be validated in bigger studies. A dedicated pulmonary nodule service is valuable in assessing incidental SSNs according to published guidelines and risk stratify patients.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/48/suppl_60/PA3810}, eprint = {https://erj.ersjournals.com/content}, journal = {European Respiratory Journal} }
