Multi-slice spiral CT findings of primary pulmonary lymphoma / 中国医师进修杂志

ABSTRACT

Objective To summarize the imaging features of multi-slice spiral CT (MSCT) in primary pulmonary lymphoma (PPL),in order to provide effective imaging diagnostic basis for clinical diagnosis.Methods The MSCT findings of 11 patients with PPL in Dalian Municipal Friendship Hospital from January 2010 to March 2019 were retrospectively analyzed.Results Among the 11 patients,pulmonary non-Hodgkin lymphoma was in 9 cases,of which pulmonary mucosa-associated lowgrade marginal zone B-cell lymphoma (MALT lymphoma) was in 7 cases,pulmonary diffuse large B-cell lymphoma (DLBCL) was in 2 cases,and pulmonary Hodgkin lymphoma was in 2 cases.Single lesion was in 2 cases,and multiple lesions was in 9 cases.Nodules and mass type was in 6 cases,solid type in 2 cases,interstitial type in 1 case,and mixed type was in 2 cases.Consolidations with air bronchogram was in 6 cases,ground-glass opacity like nodules in 3 cases,angiogramsign in 4 cases,perilymphatic and/or peribronchovascular spread in 4 cases,and lymphadenopathies were in 2 cases.Conclusions Although the imaging diagnosis of primary lung lymphoma is difficult,MSCT has certain characteristics,and improving the identification of corresponding signs has certain guiding significance for clinical practice.
