ABSTRACT
OBJECTIVE:
To evaluate the inter-group differences in growth and the pathological results of nodular ground-glass opacities (GGOs) according to their size and focal solid portions. MATERIALS ANDMETHODS:
Ninety-six nodular GGOs in 55 individuals followed by CT for at least one month from an initial chest CT were included. Forty nodular GGOs in 30 individuals were pathologically confirmed to be adenocarcinoma (n = 15), bronchioloalveolar carcinoma (BAC) (n = 11), atypical adenomatous hyperplasia (AAH) (n = 8), focal interstitial fibrosis (n = 5) and aspergillosis (n = 1). Lesions were categorized based on high-resolution CTfindings:
pure nodular GGO (PNGGO) 10 mm, mixed nodular GGO (MNGGO) 10 mm. In each group, the change in size during the follow-up period, the pathological results and the rate of malignancy were evaluated.RESULTS:
Three MNGGO lesions, and none of the PNGGO, grew during the follow-up period. Resected PNGGOs 10 mm were focal interstitial fibrosis (n = 4), AAH (n = 2), BAC (n = 2), and adenocarcinoma (n = 2). Resected MNGGOs 10 mm were adenocarcinoma (n = 11), BAC (n = 3), and aspergillosis (n = 1).CONCLUSION:
Mixed nodular GGOs (MNGGOs) had the potential for growth; most were pathologically adenocarcinoma or BAC. By contrast, PNGGOs were stable for several months to years; most were AAH, BAC, or focal interstitial fibrosis.
