Abstract：Objective: To evaluate Multi-slice computed tomography features and pathological basis of lung cancer associated with cystic airspaces, and to improve understanding of such kind of lesions and to improve diagnostic accuracy. Methods: Eighteen cases surgery pathologically confirmed lung cancer associated with cystic airspaces were retrospectively analyzed with regard to Multi-slice computed tomography features and compared with pathology. Results: There were 18 cases(peripheral lung cancer, 17 adenocarcinoma, 1 squamou carcinoma). Common CT signs: lung cancer with cyst, thin or thick and unsmooth cystic wall. The lesion was predominant cysts in 5 cases, cysts and ground-glass nodule mixed lesions in 2 cases, cysts with ground-glass nodule and solid mixed lesions in 3 cases, cysts and solid mixed lesions in 8 cases. Cysts with mural nodules, septum and blood vessel passing were 61.1%, 66.7% and 11.1% respectively. Lobulation sign and speculation sign were 50% and 55.6% respectively. Vascular convergence sign and pleural indentation sign were 38.9% and 50% respectively. One lesion showed ground-glass opacity in cyst in dynamic follow-up. The cyst cavity gradually increased and cystic wall irregular thicken in one case. Three lesions showed decreased size of the cyst and enlarged nodules. Cyst with ground-glass nodule and solid mixed lesions in one case developed to cyst with solid mixed. Conclusion: The features of lung cancer associated with cystic airspaces have certain characteristics, dynamically follow-up analysis the shape of the cyst cavity and surrounding performance is helpful for diagnosis.
