Abstract：【Objective】 To analyze the features of multi-slice CT images in patients with thin-wall cavity lung cancer during clinical follow-up.【Methods】Nine patients (male/ female, 6 /3; age range, 53 ~ 77 years) who were confirmed as thin-wall-cavity typed lung cancer by post-operative pathology were collected into this study. Their CT images in the course of clinical follow-up were reviewed retrospectively. 【Results】 At first CT examination , the maximum diameter of lesions in 9 cases of cavity type lung cancer was 1.5~4.5(2.9±0.96)mm , and the wall thickness was 1.5～4.5 ( 2.9 ± 0.96 ) mm. Mural nodules were found in 9 cases, and the mean diameter of the mural nodules was 1.59 ±24.2mm(11.4 ±6.75)mm. Typical CT features of 9 cases of cavity lung cancer include: there were 6 cases with irregular contour(66.7%), 4 cases with burr on the edge of the lesion(44.4%), 4 cases with pleural line sign(44.4%), 9 cases with luminal wall nodule(100%), 5 cases with intraluminal septum(55.6%). In 4 cases of cavity lung cancer, lesions and wall nodules gradually increased and irregular thickening was found during clinical follow-up.【Conclusion】 Cavity type lung cancer is characterized by irregular thin-walled cavity with wall nodule or / and intraluminal stripe separation. The clinical follow-up of cavity type lung cancer showed progressive thickening of cavity wall and enlargement of wall nodule.
