摘要
目的探讨多排螺旋CT对创伤性肺假性囊肿的诊断价值。方法对连续收治的42例创伤性肺假性囊肿患者进行MSCT检查,回顾性分析创伤性肺假性囊肿的CT表现。结果 42例患者经MSCT检测共发现98个病灶,多发病灶26例,单发性病灶16例。病灶位于上肺37个(37.8%),中下肺61个(62.2%),54个(55.1%)位于胸膜下区,中心区44个(44.9%)。病灶呈圆形或类圆形69个(70.4%),不规则形29个(29.6%)。98个病灶中,MSCT发现气囊肿33个(30.7%),气液囊肿50个(51.0%)和血肿15个(15.3%),病变周围可见不同程度肺挫伤改变。42例患者均有2~5次CT复查,大部分病变一周后缩小。动态随访发现气囊肿可演变为气液囊肿或血肿,气囊肿可演变为血肿,及血肿向气液囊肿逆向演变。不伴有大量血气胸的26例(61.9%)局灶型患者平均住院15天,伴有大量血气胸的16例(38.1%)复杂型患者平均住院48天,平均住院时间存在统计学差异(P=0.00)。结论 MSCT是诊断创伤性肺假性囊肿及随访的最佳影像学方法,对临床治疗具有重要指导价值。
Objective To discuss the clinical value of multi-slice spiral CT（ MSCT） in the diagnosis of traumatic pulmonary pseudocysts（ TPPs）. Methods The pulmonary imaging data of 42 consecutive patients with traumatic pulmonary pseudocysts,which were performed with MSCT,were retrospectively analyzed. Results 98 lesions in 42 patients with solitary cysts in 16 cases,and multiple cysts in 26 cases were found. Their locations included upper lobe（ n = 37,37. 8%）,middle and lower lobe（ n= 61,62. 2%）. Among 98 lesions,54 lesions were close to the pleura,and 44 in the lung central region,which were round,oval（ n = 69,70. 4%） or irregular（ n = 29,29. 6%） in shape. The CT findings included 33 lesions of traumatic gas cyst,50 lesions of gas-fluid cyst and 15 lesions of hematoma of all 98 lesions complicated with various degree pulmonary contusion around the lung laceration. All 42 patients had 2 ~ 5 CT reviews,and most lesions were reduced in size a week after. The CT dynamic observation showed gas cyst lesions could change to gas-fluid cyst or hematoma,gas-fluid cyst to hematoma,and reverse evolution lesions from hematoma to gas-fluid cyst was found. Focal type TPPs without severe hemopneumothorax was assessed in 26 patients（ 61. 9%） with the average 15 days in hospital,complex type TPPs with severe hemopneumothorax in 16 patients（ 38. 1%） with the average of 48 days in hospital,and the difference between the days in hospital was statistical significant（ P = 0. 00）. Conclusion MSCT is the best technique of choice in diagnosis and follow-up of traumatic pulmonary pseudocysts,which plays an important role in the guidance of treatment planning.
