摘　　要：目的：认识宫外孕的CT表现。方法：回顾性分析经手术、病理证实的33例宫外孕患者的CT表现,其中右侧输卵管壶腹部妊娠破裂患者20例,并左侧输卵管慢性炎症患者5例,失血性贫血患者8例;左侧输卵管妊娠破裂患者11例;左侧输卵管妊娠未破裂患者2例。年龄为17～39岁,平均年龄为25岁。结果：31例输卵管妊娠破裂者主要CT表现：①附件区见混杂密度包块,内有CT值为10～30Hu的孕囊及胚胎组织影,周围有大小不等的CT值为70～100Hu的积血影。②子宫周围见CT值为70～100Hu的积血影。③子宫直肠隐窝内见CT值为70～100Hu的积血影或CT值为10～30Hu的积液影。④子宫稍大或形态、大小未见明显异常。2例输卵管妊娠未破裂者CT表现：仅附件区见一直径1.0～3.0cm的CT值为10～30Hu的孕囊及胚胎组织影。结论：临床表现、体征、妊娠实验典型者CT常可对宫外孕进行正确诊断;对症状不典型者,综合CT图像上病灶部位、形态及密度改变、病变的范围及邻近结构的变化,亦可提出宫外孕破裂的诊断。Objective：To recognize the CT manifestations of ectopic pregnancy. Methods：Thirty-three cases（17-39 years old,an average age of 25 years old） with ectopic pregnancy proved by pathology were retrospectively analyzed,wherein 20 cases with right pars ampullaris of fallopian tube pregnancy crack（5 cases combined with left adnexitis and 8 cases combined with chronic inflammations in the left fallopian tube）,11 cases with left pars ampullaris of fallopian tube pregnancy crack,and 2 cases with left fallopian tube pregnancy but without crack. The CT manifestations of them were analyzed. Results： The main CT findings of 31 cases with tubal pregnancy crack were as following：（1） there was a mixed intensive mass in the accessory area,and a gestational sac and embryonic tissue shadow with a CT value of 10-30Hu could be seen in it and several of hematocele shadows with different sizes around uterus C with the CT value of 70-100Hu could be seen out of it.（2） The hematocele shadow around uterus with the CT value of 70-100Hu could be seen.（3） The hematocele shadow with the CT value of 70-100Hu or effusion shadow with the CT value of 10-30Hu in uterine pouch could be seen.（4） Uterus was slightly larger or normal. The CT findings of 2 cases with tubal pregnancy but without crack were only as following： a gestational sac and embryonic tissue shadow with the CT value of 10-30H could be seen in the accessory area. Conclusions： Ectopic pregnancy could be diagnosed prior to operation according to its typical clinical manifestations. CT examination may be valuable for the diagnosis of atypical cases.
