Looking for Lepidic Component inside Invasive Adenocarcinomas Appearing as CT Solid Solitary Pulmonary Nodules (SPNs): CT Morpho-Densitometric Features and 18-FDG PET Findings

<div>CT (a-d) and 18-FDG PET-CT (e, f) images of a 18-FDG PET false negative lung adenocarcinoma with lepidic predominant component; the solid nodule presented spiculated margins and notch sign (a and b, lung window), intense CE (97 HU) (c, mediastinal window) despite very low SUVmax (0.2) at 18-FDG PET examination (e, f); 1 year before the same nodule appeared as a ground-glass opacity on CT scan (d).</div>
