Abstract: Objective To analyze clinical and CT manifestations of mediastinal type lung cancer,in order to improve the under-standing of its CT signs.Methods 12 cases with mediastinal type lung cancer proved by pathology were analyzed retrospectively.Re-sults The mediastinal type lung cancer can be classified as central type (6 cases),peripheral type (4 cases)and hiding type (2 cases).There were 5 cases in the right upper lung,4 cases in the left lung and 3 cases in the lower lobe of right lung.CT showed irregular soft tissue masses adjacent mediastinum with size of 3-10 cm.7 cases showed homogeneous density and 5 cases showed heterogeneous density.The tumor and lung tissue interface was blurred in 8 cases and clear in 4 cases.5 cases had atelectasis.6 cases showed mediastinal lymph nodes enlargment.Conclusion Mediastinal type lung cancer has relatively specific clinical and CT manifestations;it can help to dif-ferential diagnosis with mediastinal tumors to understand these signs.
