    Abstract

    Objective: To analyze CT and pathological features of bronchopulmonary carcinoid and to explore the pathological foundation of its CT manifestations. Methods: The data from 32 cases of primary bronchopulmonary carcinoid diagnosed by surgery and pathology were retrospectively studied, and the features in CT scan and pathology were analyzed. Results: In this study, there were 21 cases of central carcinoid tumor and 11 cases of peripheral tumor. The maximum diameter of the lesions was 1 to 6.6cm. The lesions were round or ovoid in 17 cases, lobulated in 9 cases and irregular in 6 cases. The border of the lesions was clear, and the margin was smooth. Calcification was found in 6 cases. Ten cases received enhancement scanning, and the CT value of more than half of them increased by more than 50 Hu with an average increased value of 43 Hu. Conclusion: The features of bronchopulmonary carcinoid in CT scan are in accordance with their pathology. The CT scan shows that the border of the tumor is clear, the margin is smooth, and calcification and obvious enhancement are common. Parallel signs and mucoid impaction can also be found. The features above are helpful in using CT to diagnose bronchopulmonary carcinoid.
