Abstract:
Objective To investigate of the radiological manifestations in congenital cystic adenomatoid malformation (CCAM) of lung in adult and to improve the diagnostic accuracy of CCAM of lung in adult.Methods Five cases with pathologically proved CCAM of lung in adult were retrospectively analyzed.Chest X-ray was available in 5 cases and chest CT was performed in 2 cases.Results On plain chest radiography,thin wall air cystic lesions with air-fluid level were detected in 3 cases.Honeycomb like small cystic lesion was detected in 1 case.Multiple round cystic lesions were found in 1 case.CT scan of the chest demonstrated a round thin wall air cystic lesion in the lateral segment of right lung's middle lobe,and a thin wall air cystic lesion with the wall merged into the shadow of chest wall in the left apicoposterior segment in one case.Small cystic lesions just like honeycomb were found in bilateral basal segments of the inferior lobes,with a 0.8—1.0 cm sized round mass revealed in the right lung′s inferior lobe basal segment, and the mass was spiculated in another case.Conclusion The imaging signs of CCAM of lung in adult is cyst or cyst-solid and at the risk of developing carcinoma.
