[CT scan findings of primary pulmonary non-Hodgkin's lymphoma and their relation to pathological features].
To investigate the CT scan findings of primary pulmonary non-Hodgkin's lymphoma (PPNHL) and their relation to pathological features.



The CT scan findings of 17 PPNHL cases confirmed pathologically from August 1992 to June 2007 were analyzed in relation to their pathological foundation.



In 17 cases the CT findings showed: 1) Five were single mass or nodule, including 3 with air-bronchograms, 1 with straddling-lobe distribution and 3 with slight enhancement; 2) One was multi-nodules with air-bronchograms; 3) Six were consolidation with air bronchogram,including 3 with straddling-lobe distribution and 3 with slight enhancement; 4) Five were combined changes, including 5 with air-bronchograms, 2 with straddling-lobe distribution and 4 with slight enhancement. The CT features of PPNHL corresponded to their pathological process and pathological features.



Primary pulmonary non-Hodgkin's lymphoma should be considered when CT scan shows variety of images found in one patient, middle lobe of right lung involved, air-bronchograms and straddling-lobe distribution in consolidation with slight enhancement.
