ABSTRACT
PurposeTo discuss the imaging features of multi-slice spiral CT (MSCT) and PET/CT in lymphoma with pulmonary lesions as the initial presentation.Materials and Methods Eighteen cases of lymphoma with pulmonary lesions as initial presentation confirmed by operation and pathology were retrospectively analyzed including Hodgkin lymphoma (HL) in 3 cases and non-Hodgkin lymphoma (NHL) in 15 cases. All 18 patients underwent MSCT, of which 11 also underwent PET/CT. The MSCT manifestations included number of lesions, morphology, density and bronchial change. PET/CT evaluated lesions in other body parts and SUVmax of lung lesions.Results MSCT showed single lung lesion in 6 cases, multiple lung lesions in 12 cases. Masses were seen in 9 cases, non-masses in 7 cases, and mixed type in 2 cases. There was single consolidation in 3 cases and mixed consolidation in 15 cases. Air bronchogram was identified in 15 cases. CT predictive diagnosis was lymphoma in 3 cases, lung cancer in 5 cases, pneumonia in 7 cases, granuloma in 1 patient, and indeterminate in 2 cases. PET/CT showed hypermetabolic lung lesions in 11 patients, mediastinal lymph node in 3 cases, and unilateral supraclavicular lymphadenopathy in 1 case. One patient showed pancreatic tail masses, gastric wall thickening and haunch masses. All 11 patients were diagnosed as malignant tumor, of which 8 cases as lymphoma.Conclusion MSCT manifestations of lymphoma with pulmonary lesions as initial presentation include multiple lesions, polymorphic type and heterogeneity with air bronchogram. PET/CT has better accuracy than MSCT.
