To assess the performance of high-resolution computed tomography (HRCT) in discriminating consolidation pattern pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma from lobar pneumonia.This retrospective study comprised 26 patients with pathologically confirmed MALT (12 men and 14 women; mean age, 59.4±12.1 years) 36 pneumonia by body fluids or respiratory secretion culture (16 20 41.8±26.3 years). Two radiologists independently evaluated CT images. The effectiveness these variables distinguishing was analyzed using logistic regression analysis.The average age younger than that (p=0.002). symptom more common Signs bronchiectasis within bulging interlobar fissure occurred significantly often (69.2% vs 11.1%, p<0.0001; 46.2% 19.4%, p=0.024). We used predictors p<0.05 (age, symptoms, bronchiectasis, fissure) to construct a model. area under curve (AUC), negative predictive value (NPV), positive (PPV), sensitivity, specificity, accuracy were 0.891, 84.21%, 83.33%, 88.89%, 76.92%, 83.87% for lymphoma.Middle-aged, presence mild clinical on chest images are potential markers distinguish pneumonia.
