Abstract
PURPOSE: Primary pulmonary lymphoma(PPL) arising in the lung as the initial site is very rare. Authors experienced two cases of PPL and report the radiologic findings and clinical characteristics with a brief reviewof the literature.
METHODS AND MATERIALS: Plain chest radiograph and enhanced axial CT scan of the chest were taken. We analyzed radiologic findings of the two cases and correlated with broncoscopic and pathologic findings.
RESULTS: Plain chest radiograph showed a mass like consolidative lesion on RML without peripheral atelectasis. Chest CT scan revealed a mass like consolidation with airbronchogram and the absence of a hilar mass or thoracic adenopathy. Percutaneous needle aspiration and biopsy(PCNA and PCNB) of the RML mass confirmed B-cell lymphoma, in both cases.
CONCLUSION: PPL must be included in the differential diagnosis of chronic alveolar consolidation such as bronchioloalveolar cell carcinoma.
