Objective To summarize CT findings of bronchial carcinoids and raise awareness of the disease. Methods The clinical and CT findings of 25 cases of pathologically confirmed bronchial carcinoids were retrospectively analyzed. Results There were 25 cases of typical carcinoid in 25 cases and 8 cases of atypical carcinoid in the whole group. There were 17 cases of central type, of which 8 cases originated from leaf bronchus, 7 cases were segmental bronchus, 2 cases were main bronchus, 8 cases were peripheral type. The central type of carcinoid tumor is small, with a diameter of 0.5 to 32cm (average of 19cm), smooth edges, and calcification in 1 case. Peripheral carcinoid tumors are larger, with a diameter of 20 to 18 0 cm (average 54 cm), smooth edges, and common necrosis areas within the tumor. Conclusion Chest CT scan is very valuable for the display of bronchial carcinoid, and the diagnosis needs to be combined with clinical
