Part of the Syllabus book series (SYLLABUS)


Among the noninvasive methods, the only valid proof of the benignity of a solitary pulmonary nodule (SPN) is an absence of growth for more than 2 years, documented by plain films or computed tomography (CT) [1]. A size inferior to 0.8 cm is no longer considered as a statistically reliable indicator of benignity [2], 42% and 15% of malignant SPN being less than 2 and less than 1 cm, respectively [2]. In contrast, the vast majority, over 95%, of SPN larger than 3 cm are malignant.
