肺純磨玻璃結(jié)節(jié)微浸潤腺癌與浸潤性腺癌的CT鑒別診斷
[Abstract]:Objective to investigate the CT differential diagnosis of pulmonary microinvasive adenocarcinoma (MIA) and invasive adenocarcinoma (IAC) with pure ground-glass nodules (pGGN). Methods the clinical and CT data of 32 cases of MIA and 66 cases of IAC confirmed by operation and pathology were analyzed retrospectively. The age, sex, maximum diameter, density, morphology, edge, internal and adjacent structure of the lesions were analyzed. Statistical analysis was carried out. Results there was no significant difference in age and sex between MIA and IAC (P 0.05), but there was no significant difference in the maximum diameter, density, morphology, clear tumor-lung interface between the two groups (P 0.05), lobulation sign and burr sign. There were significant differences between the two groups in air bronchus sign (P < 0.05), dilatation-like change (P < 0.05) and vascular cluster sign (P < 0.05). Conclusion when the lesion of pGGN is accompanied by lobulation, burr sign and air bronchus sign, the possibility of IAC is higher when the bronchus of pGGN is distorted, dilatation like change and vascular cluster sign.
