输卵管系膜囊肿的CT表现及误诊分析

Analysis of CT Manifestations and Misdiagnosis of Mesosalpinx cyst

目的探讨输卵管系膜囊肿的CT表现,分析常见误诊原因,提高对本病的认识和诊断。方法回顾性分析5例经病理证实的输卵管系膜囊肿病例的临床资料和CT表现,并结合相关文献。结果 5例患者的CT图像上,2例位于子宫左旁,3例位于子宫右旁;囊肿4例为类圆形或椭圆形,1例为上宽下细囊样影;CT值为0-10HU不等,境界清晰,囊壁光滑,无壁结节,1例有分隔;囊内未见强化。2例伴有子宫肌瘤,2例伴有患侧输卵管积水。结论首先要提高对本病的认识,再者囊样或上宽下细腊肠样或蛇形样囊样影,境界清晰,水样密度,无壁结节,为输卵管系膜囊肿的主要征象。

Objective To investigate CT manifestations of mesosalpinx cyst and analyze reasons of misdiagnosis.To improve the diagnostic level of this disease.Materials and Methods The clinical data and CT manifestations of 5 cases which were confirmed by pathology were retrospectively analyzed,and the concerned literatures were reviewed.Results Of the 5 patients,the lesion showed on the left side of the uterus in 2 cases,on the right side of the uterus in 3 cases.Cysts showed round or oval shadow in 4 cases,and saclike shadow which were wide at the top and narrow at the bottom in 1 case.CT values were ranging from 0 to 10Hu.The lesion had clear boundary and smooth wall without nodule.1 case showed separation line.In enhanced scan,capsule contents showed no enhancement.2 cases associated with uterine fibroids,and 2 cases with hydrosalpinx on the affected side.Conclusion First of all,we should aware of the existence of this disease.Cystic,sausagelike or snake-like shadow with clear realm,water density and without mural nodules was the main signs of the mesosalpinx cyst.
