Abstract:
Objective To investigate the high resolution CT (HRCT) findings of pleura invasion of lung adenocarcinoma (stageⅠ) presenting as mixture ground glass nodule (mGGN).Methods 20 cases of lung adenocarcinoma presenting as mGGN were confirmed by pathology.The correlation of those cases with pleural adjacent relation and the relation between the maximum diameter and pleural invasion were analyzed retrospectively.Results (1)The classification of mGGN adjacent to the pleura relationship:type Ⅰ,typical and atypical pleural retraction sign,10 cases of this type did not show pleural invasion;type Ⅱa,the mGGN contacted pleural for ground glass opacity,4 cases of this type showed no pleural invasion;type Ⅱb,the mGGN contacted pleural for solid elements,6 cases of this type were with pleural invasion.(2)The difference of the maximum diameter of mGGN in groups pleural invasion and non-invasion was not significant statistically (P=0.694).Conclusion The mGGN contacted pleural for solid composition is a reliable sign in diagnosis of pleural invasion.
