Abstract: Objective To investigate the CT features of pulmonary mucosa-associated lymphoid tissue (MALT)lymphoma. Methods The data of 20 cases with pathologically confirmed pulmonary MALT lymphoma were collected.All cases underwent CT plain and enhanced scan,and the CT features were analyzed retrospectively.Results Among the 20 cases,15 cases showed multiple consolidations,accompanied by mass and small nodules,1 case had solitary consolidation with multiple micronodules,2 cases had solitary consolidation,2 cases had diffuse micronodules.The sign of dilated air bronchograms was found in 10 cases with pulmonary consolidation lesions, reaching the margin of lesion.All lesions and masses were mildly and moderately homogenous enhanced.Pulmonary thin-wall cystic cavity was seen in 7 cases of diseased tissue and surrounding lung tissue.Conclusion CT manifestation of pulmonary MALT lymphoma mainly shows multiple lung consolidation,which includes the signs of consolidation with dilated air bronchograms,homogenous enhancement, and accompanying with signs such as mass,micronodules and pulmonary thin-wall cystic cavity.
