Objective To investigate the chest radiographs and CT findings of primary pulmonary sarcoma and to improve the diagnostic accuracy. Methods The clinical and imaging data of 14 patients with primary pulmonary sarcoma confirmed by surgery and pathology were retrospectively analyzed. Results The main clinical manifestations of 14 cases of primary pulmonary sarcoma included 11 cases of cough, 9 cases of chest pain, 9 cases of hemoptysis and 6 cases of chest tightness. All 14 cases of chest radiographs were single lesion, the diameter of lesion was 4 ~ 123 cm and the density was uniform , No lymph node enlargement, 11 cases were round or oval, the edge of 10 lesions was smooth and clear, 4 cases showed lobulation, no burr; 9 cases were examined by CT, the diameter of the lesion size ranged from 49 to 128 cm 5 cases of uniform density, 4 cases of density less uniform, showing central necrosis or calcification, 3 cases were round, 6 cases of irregular shape, 9 cases of smooth edges, 3 cases of edge fuzzy, with local violations, 5 cases were visible Ye Zheng, injection of contrast agent after 6 lesions were significantly enhanced. Conclusion The clinical manifestations of primary pulmonary sarcoma nonspecific, chest X-ray or CT showed a clear outline of the tumor, the edge of the smooth, more than 4cm in diameter, may have central necrosis, calcification and local violations, enhanced CT was significantly enhanced, late visible hilar Or mediastinal lymph nodes
