肺撕裂伤的CT表现和动态观察

CT Findings and Dynamic Analysis of Pulmonary Laceration

摘要: 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。

Abstract: 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.
