摘要
目的通过卵巢肿瘤MRI与手术病理对照观察,探讨MRI在诊断卵巢肿瘤方面的应用价值。方法经手术病理证实的卵巢肿瘤患者38例,术前均做MRI检查,详细分析总结其MRI表现特点,并与手术所见进行对照。结果 38例中良性肿瘤16例,恶性肿瘤22例。在肿瘤的最大径(P=0.499)和内部信号(P=0.066)方面,良、恶性肿瘤之间没有差别。在卵巢单侧或双侧受累(P=0.009)、肿块形态(P=0.000)、囊壁是否均匀(P=0.000)、有无壁结节(P=0.025)、与邻近脏器分界清楚与否(P=0.008)、肠管及大网膜是否受累(P=0.005)、盆腔淋巴结是否肿大(P=0.000)、有无腹腔积液(P=0.000)方面有显著性差异。卵巢恶性肿瘤,在显示大网膜是否受累(P=0.031)、盆腔淋巴结有无肿大(P=0.045)方面,MRI与手术所见有显著性差异;在肠管受侵方面,有5例诊断不正确,但统计学上无差异(P=0.227)。结论 MRI对卵巢肿瘤的诊断有重要作用,但在判断大网膜受侵、盆腔淋巴结肿大方面存在一定局限性。
Objective To discuss the application value of MRI in diagnosing ovarian tumor compared with surgical pa- thology. Methods MR findings of 38 cases with ovarian tumor proved by surgical pathology were analyzed retrospectively, MR findings were compared with the operation results. Results Of 38 cases, there were benign tumor in 16 cases and malignant tumors in 22 cases. There was no difference in the biggest diameter in tumor （ P = 0.499） and internal signal （ P = 0.066） between the benign and malignant tumor. There were significant differences in ovarian unilateral or bilateral involvement （ P = 0.009 ） , mass shape （ P = 0. 000） , bursa wall（ P = 0.000 ） , wall nodules （ P = 0. 025 ） , margin be- tween adjacent organs （ P = 0. 008 ） , bowel and omental involvement （ P = 0. 005 ） , pelvic lymph node （ P = 0. 000） , as- cites （P = 0. 000） between the benign and malignant tumor. There was significant difference in omental involvement （P = 0.005 ） and pelvic lymph node （ P = 0. 000 ） between MRI and operation results. 5 cases diagnosed by MRI were not cor- rect in evaluating bowel or not, but there was no statistically difference between them （ P = 0. 227 ）. Conclusion MRI has an important role in diagnosing ovarian tumor, but it also has certain limitations in judging violated omental and pelvic lymph node.
