There are limited studies on imaging features of pulmonary MALT lymphoma. We present the computed tomography (CT) manifestations of pulmonary MALT lymphoma and the correlation between CT manifestations and clinical characteristics. Patients (n\u2009=\u200953) with histologically confirmed pulmonary MALT lymphoma who underwent chest CT scanning were retrospectively analyzed. Evaluated findings included distribution of pulmonary lesions, morphological pattern of appearance, contrast enhancement features, size, presence of thoracic lymphadenopathy, and secondary associated features. Pulmonary MALT lymphoma was observed in multiple (79%) and bilateral (66%) disease with random distribution (\u226570%) of pulmonary lesions. The most frequent morphological pattern was consolidation (n\u2009=\u200933, 62%), followed by nodule (n\u2009=\u200923, 43%) and mass (n\u2009=\u200911, 21%). Common associated features were air bronchograms and bronchiectasis, especially cystic bronchiectasis and angiogram sign. Asymptomatic patients had less consolidation and bronchiectasis than did symptomatic patients. Cystic bronchiectasis was only observed in the symptomatic group. In conclusion, pulmonary MALT lymphoma manifests as diverse patterns on CT scans. Consolidation combined with cystic bronchiectasis was a characteristic late sign, which may assist in differential diagnosis. High-resolution CT images and multiplanar reconstruction techniques are helpful for accurately determining imaging manifestations.<\/jats:p>","DOI":"10.1038\/s41598-019-45144-9","type":"journal-article","created":{"date-parts":[[2019,6,17]],"date-time":"2019-06-17T06:03:05Z","timestamp":1560751385000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":49,"title":["Pulmonary MALT Lymphoma has variable features on CT"],"prefix":"10.1038","volume":"9","author":[{"given":"Wen","family":"Deng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Wan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian-qun","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2019,6,17]]},"reference":[{"key":"45144_CR1","doi-asserted-by":"publisher","first-page":"53","DOI":"10.1148\/rg.2016140339","volume":"36","author":"A Sirajuddin","year":"2016","unstructured":"Sirajuddin, A. et al.
