RÉSUMÉ

Objective: To explore the characteristic of the imageological sign of multi-slice spiral CT in diagnosing thin wall cystic lung cancer. Methods: 42 patients with thin wall cystic lung cancer who underwent thin layer CT scan were enrolled in the research. And all of them were divided into parenchyma group (22 cases) and non-parenchyma group (20 cases) according to the composition of cancer tissue density. And retrospective analysis was applied to compare the imageological signs of the patients in two groups. Results: The occurrence rates of roundness, quasi-circular, spicule sign at margin and truncation sign of bronchus were 95.5%, 59.1% and 68.2% in parenchyma group, respectively. And they were significantly higher than that (65.0%, 10.0% and 5.0%) of non-parenchyma group (x2=4.481, x2=13.793, x2=17.733, P<0.05). And the occurrence rates of ground glass sign, bronchus in cystic space and blood vessel passing the interior of cystic space were 27.3%, 9.1% and 18.2% in parenchyma group, respectively. And they were significantly lower than that (75.0%, 40.0% and 70.0%) of non-parenchyma group (x2=9.546, x2=3.945, x2=11.486, P<0.05). Conclusion: The CT examination of thin wall cystic lung cancer has characteristic in a certain extent, and it can combine CT to dynamically follow up the change and pathological manifestation so as to carry out diagnosis.
