Abstract

Abstract:

Objective

To analyze the characteristics of multilayer spiral CT (MSCT) images of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma for improving the diagnostic accuracy.

Methods

The MSCT findings of 16 patients with lung MALT lymphoma pathologically confirmed were analyzed retrospectively.

Results

Among the 16 patients, 6 patients suffered from single lung MALT lymphoma and 10 from multiple ones. According to the MSCT morphology, MALT lymphomas were divided into three types: nodular/mass pattern in 7 cases, exudate/consolidation pattern in 6 cases and mixed pattern in 3 cases. Fourteen cases showed thickened vascular bronchial bundle around the lesions, and 8 cases showed calcification within the lesions. And 11 cases had air bronchial sign, including 9 cases of bronchiectasis. Four cases of nodular/mass pattern showed drilled-like growth. Among the 16 patients, 13 patients received enhanced scanning, including 11 patients receiving uniform enhancement, and as a result, 11 patients showed angiogram sign. Three cases had enlarged mediastinal lymph nodes and 8 cases had pleural effusion.

Conclusion

The MSCT of lung MALT lymphoma has certain characteristics, therefore, the lung MALT lymphoma can be diagnosed combined with the clinical manifestation of inert growth.
