摘要
目的：提高对女性盆腔占位病变的MR表现的认识，评价其诊断及鉴别诊断价值。方法：回顾性分析92例（156个病灶）经术后病理证实的盆腔占位病变的MR征象。结果：MRI共检出病灶146个（146/156，93.6％），其中子宫病变84个（84/85，98.8％），卵巢病变61个（61/70，87.1％），直肠癌1个，2个子宫肌瘤、5个卵巢冠囊肿、3个黄体囊肿漏诊（10/156，6.4％）。MRI检出的146个病灶中，145个病灶部位均与病理符合，准确性为99.3％。子宫病变主要表现为实质性肿块影或子宫内膜增厚；卵巢病变表现为囊性、囊实性或实性肿块影。MRI诊断为良性病变108个，恶性病变38个；病理诊断良性病变116个，恶性病变40个，MRI诊断出恶性病变的灵敏度为95.0％（38/40），阳性预测值为100％。结论：MRI对盆腔病灶的定位具有很高的准确性，在定性方面，判断良恶性肿瘤亦具有较高的准确性，但是区分恶性肿瘤的细胞类型难度较大。
Abstract
Objective: To improve the recognition and diagnosis and differential diagnosis of MRI for female pelvic mass occupying diseases. Methods: To review the characteristics of MRI in 92 case of female pelvic occupying diseases(156 lesions) proved by pathology. Results: A total of 146 masses(146/156, 93.6%) were detected by MRI, including uterus diseases, 84 cases(84/85, 98.8%), ovarian diseases 61 cases(61/70, 87.1%) and rectal cancer 1 case, lesions not detected by MRI: 2 leiomyomas, 5 parovarian cysts and 3 corpus luteum cysts. For 146 masses, the location of 145 were consistent with pathology, the accuracy was 99.3%. Uterus diseases mainly demonstrated as solid tumor masses or endometrial thickening, ovarian diseases mainly demonstrated as cystic or cystic and solid or solid masses. In MRI, benign lesions were 108, malignant lesions were 38, while in the pathologic findings, benign lesions were 116, malignant lesions were 40, the sensitivity of MR in the diagnosis of malignant lesions was 95.0%(38/40), and the positive predictive value was 100%. Conclusion: MR can evaluate the origin of pelvic lesions with high accuracy as well as distinction between benign and malignant lesions, but there was some difficulty to diagnose cell types.
