Abstract:
Objective To explore the MSCT manifestations of pulmonary focal ground-glass opacity (GGO)nodules with differ-ent pathological types.Methods The thin-layer CT images of 87 patients with GGO nodules were retrospectively reviewed.Of them, 57 cases were confirmed by surgery and pathology,including 8 inflammations,2 benign tumors,1 1 adenomatous hyperplasias (AAH),1 9 carcinomas in situ (AIS),and 1 7 adenocarcinomas.The other 30 cases were followed up without surgery.Results Blur edge was found in 6 of the 8 inflammations (75.0%).However,the organized pneumonias showed large irregular shape with clear edge.Of 30 pre-infiltrating lesions (AAH or AIS),28 (93.3%)were ranged from 0.8 cm to 2.0 cm,26 (86.7%)were round or nearly round,25 (83.8%)showed clear edge,and 25 (83.8%)had blood vessels penetrated signs.Of 17 adenocarcinomas,15 (88.2%) were larger than 2.0 cm,13 (76.5%)showed irregular or lobular shape,8 (47.0%)showed coarse edge,and 10 (58.8%)had pleural indentation signs.Of 36 AISs and adenocarcinomas,9 were solid components (specificity of 95.2%),5 had vacuole signs (specificity of 95.2%),and 13 had penetrated and enlarged blood vessels (specificity of 100%).Conclusion There are characteristic MSCT appearances for different pathological types of GGOs.
