Objective:

To investigate the CT manifestations of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma and improve the understanding of this disease.

Methods:

The clinical and imaging data of 12 cases of lung MALT lymphoma confirmed by transcutaneous lung biopsy and pathology were analyzed. All patients underwent plain CT scan of the chest.

Results:

A total of 12 cases of CT were manifested as pulmonary consolidation

of which 5 cases were solitary lesion and 7 cases were multiple lesion. The sign of dilated air bronchograms and multiple empty bubbles were seen in 11 of 12 cases with pulmonary consolidation lesions

randomly distributed multiple nodules and masses in 9 cases

multiple

cavities in 2 cases

and under subpleural abrasion with multiple ground-glass opacity in 1 case.

Conclusion:

Pulmonary consolidation was a common CT manifestation of pulmonary MALT lymphoma. It is characterized by air bronchogram sign and multiple empty bubbles with bronchiectasis. Pulmonary nodules and masses

cavities

and ground glass opacity were also one of the features of the disease.
