肺撕裂伤的CT表现和动态观察

CT Findings and Dynamic Analysis of Pulmonary Laceration

目的:探讨肺撕裂伤的CT表现。方法:回顾性分析51例肺撕裂伤患者的首次检查和治疗后复查的CT资料。结果:51例患者共249个病灶,CT表现为气囊(22个)、气液囊(182个)和液囊(45个),周围伴不同程度肺挫伤。20例患者进行CT动态观察,气囊可以演变为气液囊或液囊,气液囊可以演变为液囊,但未有逆向演变者。结论:气囊、气液囊和液囊是肺撕裂伤的典型CT表现和动态演变过程。

Objective： To investigate the CT findings of pulmonary laceration. Methods： The CT imagings of 51 cases with pulmonary laceration were analyzed retrospectively. Results： 249 lesions in total were found in the 51 patients. The CT findings included traumatic gas cyst （22 lesions）, gas-fluid cyst （182 lesions） and fluid cyst （45 lesions）. Various degree of pulmonary contusion around the lung laceration could be assessed. On dynamic follow-up observation of 20 patients, the gas cyst lesions could change to gas-fluid cyst or fluid cyst, and the gas-fluid cyst lesions could change to fluid cyst, but reversed variation was not found. Conclusion： The gas cyst, gas-fluid cyst and fluid cyst were the characteristic CT findings and dynamic morphology changes of pulmonary laceration,
