摘要
目的:分析气肿性胆囊炎(EC)的CT表现及鉴别诊断,提高对此病的诊断能力。方法:本组经手术及病理证实的EC共9例,8例行上腹部平扫,1例加行上腹部增强扫描。结果:1例CT表现为胆囊腔内积气,3例胆囊壁内积气,2例胆囊壁内积气合并胆囊腔内积气,另3例表现为胆囊壁积气及腹腔内游离气体、胆囊周围炎。结论:EC的特征性CT表现是胆囊积气(除外胆肠瘘),其CT表现多样,仔细观察并结合临床应能与有类似CT征象的病变相鉴别。
Objective：To analyze the CT appearances of emphysematous cholecystitis（EC） and its differential diagnosis,so as to improve the level of diagnosis.Methods：9 cases of surgery and histopathology proved EC were collected.8 cases underwent plain CT and one case received plain CT and enhanced CT scanning.Results：CT images showed air within the lumen（n=1）,intramural gas of gallbladder（n=3）,combination of the two above-mentioned appearances（n=2）,intramural gas of gallbladder with free pneumoperitoneum and pericholecystitis（n=3）.Conclusion：After cholecysto-intestinal fistula was excluded,various signs of pneumo-gallbladder are the characteristic CT features of EC.Proper diagnosis and differential diagnosis could be achieved by careful study of CT and clinical manifestations.
