目的提高对创伤性肺囊肿的影像学特征和临床诊断的认识。方法对14例肺撕裂伤患者进行回顾性分析。结果多发囊肿4例,单发10例,均位于肺野边缘。CT分型包括含气囊肿、液气囊肿、含液囊肿。短期周围出现多发卫星小囊肿8例,部分并有节段性肺不张,囊内密度易变、愈合期有纤维化。结论创伤性肺囊肿影像表现典型,多层螺旋CT扫描重建对病变诊断有重要价值。 Objective To improve the imaging features and clinical diagnosis of traumatic pulmonary cysts. Methods 14 cases of lung laceration were retrospectively analyzed. Results of multiple cysts in 4 cases, single in 10 cases, are located in the edge of the lung field. CT classification, including cysts, liquid cysts, cysts containing fluid. Short-term occurrence of multiple cysts in small cysts in 8 cases, some with segmental atelectasis, cystic degeneration, fibrosis during healing. Conclusions The imaging manifestations of traumatic pulmonary cyst are typical. Multi-slice spiral CT scan reconstruction has important value in the diagnosis of lesions.
