目的:探讨输卵管系膜囊肿CT表现,提高术前诊断的准确性。方法:回顾性分析经手术与病理证实的7例输卵管系膜囊肿患者的临床资料和CT表现,并复习相关文献。结果:7例患者共8个输卵管系膜囊肿,CT检出7个,位于子宫右前缘4例,子宫正前方1例,子宫右后方1例,子宫左侧1例。囊肿大小2.0cm×3.0cm~10.0cm×12.0cm,呈圆形、卵圆形,囊壁菲薄、未见壁结节,囊内呈均匀液性密度影,1例囊肿内见线状分隔。平扫囊液CT值0~15HU,增强扫描囊壁及囊内细线状分隔不强化或呈轻度延迟强化。4例合并同侧输卵管炎,1例合并纤维瘤,3例合并子宫肌瘤。结论:输卵管系膜囊肿的CT表现具有一定特点,MSCT三维重建技术(MPR)有利于本病显示,对输卵管系膜囊肿的诊断和鉴别诊断具有重要价值。
Objective: To investigate the CT findings of tubal mesangial cysts and improve the accuracy of preoperative diagnosis. Methods: The clinical data and CT findings of 7 cases of tubal mesangial cysts confirmed by surgery and pathology were analyzed retrospectively. The related literatures were reviewed. Results: A total of 8 tubal mesocyst were found in 7 patients. CT was detected in 7 of them, 4 in the right anterior margin of the uterus, 1 in front of the uterus, 1 in the right posterior uterus and 1 in the left uterus. Cyst size 2.0cm × 3.0cm ~ 10.0cm × 12.0cm, was round, oval, thin wall, no wall nodules, cystic was uniform liquid density, see a cyst linear separation. Efficacy of cyst fluid CT 0 ~ 15HU, enhanced cyst and cystic capsule thin linear separation is not enhanced or mild delayed enhancement. 4 cases of ipsilateral salpingitis, 1 case of combined fibroids, 3 cases of uterine fibroids. Conclusion: The CT appearance of tubal mesangial cyst has some characteristics. MSCT three-dimensional reconstruction (MPR) is helpful for the diagnosis of tubal mesangial cyst and is of great value in the diagnosis and differential diagnosis of tubal mesangial cyst.
