Solid Indeterminate Pulmonary Nodules Less Than or Equal to 250 mm<sup>3</sup>: Application of the Updated Fleischner Society Guidelines in Clinical Practice

<div>Solid pulmonary nodule smaller than 100 mm<sup>3</sup> with smooth margins located in the right upper lobe in a 71-year-old high-risk male patient. Baseline (left) and follow-up CT scans (right). The interval between the two CT examinations was 184 days. The software calculated significant growth between the baseline and follow-up CT scans with a relative volume variation of 292% (from 55 mm<sup>3</sup> to 216 mm<sup>3</sup>) and a volume doubling time of 93 days. The nodule was surgically removed and proven to be a pulmonary adenocarcinoma. In this case, the new Fleischner Society guidelines would have recommended a follow-up CT examination at 12 months.</div>
