Abstract：Objective: To investigate the CT manifestation of congenital cystic adenomatoid malformation(CCAM) of lung in adult. Methods: From March 2005 to November 2015, 9 patients with CCAM confirmed by postoperative pathology underwent CT scanning or enhanced CT scanning preoperatively. The CT manifestation and pathological style were analyzed. Results: The lesions of 7 cases were in the right lung, 2 cases in the left lung; 7 cases involved a single lobe, only 2 cases involved two lobes. The CT manifestations of 9 cases with CCAM included macrocystic type(diameter >2 cm) in 8 cases and microcystic type(diameter <2 cm) in 1 case. 6 cases of the macrocystic type contained less than 3 cysts with smooth wall, filled fluid. 2 cases of the macrocystic type were polycystic structure(>3), and the cyst wall was not smooth, with ridge-like protrusions and multiple separation. 1 case of microcystic type was honeycomb structures with homogenous cyst size(<2 cm). Finally, pathological results of 8 macrocystic cases were Stocker’s typeⅠ, the microcystic case was Stocker’s typeⅡ. Conclusion: The CT manifestations of CCAM had a certain characteristics, and might predict the pathological type. CT examination was useful for the preoperative diagnosis of CCAM.
