- Abstract: Objective To investigate the common CT imaging features of bronchogenic cysts. Methods A retrospective analysis was carried out on 32 cases with bronchogenic cysts confirmed by surgery and pathology. CT cross-section and multi-plane reconstruction (MPR) were used for observing the morphology, size and density of the lesions, and enhancement scan for analyzing the enhancement and adjacent relationships. Results All cases had single lesion and underwent CT examination and enhancement scan. There were 2 cases of ectopic type (neck), 28 of mediastinum type (10 of anterior mediastinum, 6 of middle mediastinum, 12 of posterior mediastinum), and 2 of intrapulmonary type. The tumors were quasi-circular or circular in 22 cases, droplet- or D-shaped in 9 cases, and irregular in 1 case. Pleural indentations were observed in 3 cases of posterior mediastinum. Negative CT value was found only in 1 case in which there was stratified and the capsule wall was arc-shaped with calcifications CT value was 0-30 HU in 20 cases and > 30 HU in 11 cases. Enhancement scan showed no enhancement in 31 cases, except 1 case of intrapulmonary type with complicated infection and obvious enhancement in the capsule wall. The combination with MPR demonstrated that the anterior mediastinum and surrounding tissues had clear boundaries. Mediastinal lesions may be closely associated with bronchi. The lesions in the posterior mediastinum were attached to the adjacent thoracic vertebra with a broad base, forming the D-sign. The adjacent bones were not affected or became thinner due to slight compression and absorption. Intrapulmonary lesions were accompanied by infection or communicated with adjacent bronchi. Conclusion The common CT signs of bronchogenic cyst are characteristic, which contribute to the accurate diagnosis.
