摘　　要：目的提高对创伤性肺假性囊肿（post—traumatic pulmonary pseudocyst，PPP）的胸部CT影像表现的认识。方法同顾性分析24例PPP的临床资料及系列胸部CT图像。结果24例中，共发现35个PPP。复查CT显示：①气囊、气液囊无转化消失16例．州互转化2例．发展为血肿17例；分组比较PPP大小,气囊组显著小于气液囊组及血肿组（P〈0．05）；②5例短期内出现大量液气胸，致使PPP缩小或消失，在肺复张后，PPP亦恢复；③所有病灶复查中均未持续增大,在11～82d内吸收。结论PPP具有从气囊、气液囊、血肿到消失的转归过程，为CT诊断肺挫裂伤的可靠依据。Objective This study aims to analyze the CT findings outcome of post traumatic pulmonary pseudocyst （PPP）. Methods The serial chest CT films and clinical data of 24 patients with PPP were retrospectively analyzed. Results Thirty five PPPs from 24 patients were found. Follow-up CT scans demonstrated： （1）The air filled cavity and air fluid cavity could change to each other or lurn into pulmonary hematoma; compared the size of lesions, air filled cavities were significantly smaller than the air fluid ones or hematoma （P〈0.05）. （2）The PPPs decreased or disappeared when larger ipsilateral pneumothorax and/or hemothorax occurred in 5 cases, but these PPPs reappeared after the resolution of hemopneumothorax. （3）The PPPs were not found to continuous enlarge and resolved in 11--82 days. Conclusion Evolution pattern of PPPs is that from the air-filled cavity, air-fluid cavity, and pulmonary hematoma to disappear. This is a reliable basis for the CT diagnosis of pulmonary contusion.
