创伤性假性肺囊肿的CT诊断价值

CT Diagnostic Value of Traumatic Pulmonary Pseudocysts

目的:探讨创伤性假性肺囊肿的CT表现及其诊断价值。方法:回顾性分析22例创伤性假性肺囊肿患者的临床资料及CT表现。结果:22例患者累及28侧肺共30个病灶,其中肺气囊肿14例,CT表现为单个或多发肺内含气囊腔,壁薄较均匀,内壁多光整;气液囊肿8例,CT表现为囊内含有积液,可见气-液平面,壁厚薄欠均匀,但内壁光整;1个月内复查CT肺内的含气或气液囊肿均有不同程度吸收变小。22例患者均伴有不同程度的胸部其他损伤,其中肺挫伤9例,肋骨骨折5例,胸腔积液15例,气胸7例,皮下气肿2例。结论:创伤性假性肺囊肿的CT表现具有一定的特征性,结合病史可确立诊断,能为临床制定治疗方案以及了解病情提供非常有意义的参考依据。

Objective：To investigate the CT manifestations and its diagnostic value of the traumatic pulmonary pseudocysts . Methods：The CT manifestations of 22 patients with traumatic pseudo cyst of lung were analyzed retrospectively .Results：In 22 cases there were 30 lesions of 28 sides.14 cases of air filled cysts ,the CT performances were a single or multiple air chambers and uniformly thin wall and inner wall finishing;8 cases of liquid and air cyst ,the CT performances were capsule of effusion ,visible air-liquid surface ,no uniform wall thickness ,but internal finishing;Followed up a month , the cysts filled with liquid and air were absorbed decrescent in all .All patients were accompanied with varying degrees of chest injury ,pulmonary contusion in 9 cases, fractured ribs in 5 cases,pleural effusion in 15 cases,pneumothorax in 7 cases, subcutaneous emphysema in 2 cases.Conclusion：Traumatic pulmonary pseudocysts have certain characteristic of CT manifestation , combined with the history may establish the diagnosis ,and can offer significant reference basis for clinical treatment as well as understanding the illness .
