We present a case of a woman with marked cystic degeneration of a uterine leiomyoma mimicking an ovarian neoplasm. Case: A 65-year-old woman (gravida 6, para 6) visited us due to an abdominal tumor. Clinical examination and radiology exploration suggested the presence of an ovarian tumour. The patient underwent a total abdominal hysterectomy with bilateral adnexectomy. Histopathology confirmed a final diagnosis of a degenerated leiomyoma. The patient’s postoperative course was uneventful and she was discharged on her 5<sup>th</sup> post-operative day. Conclusions: When a patient has a huge abdomino-pelvic mass, mimicking an ovarian tumor, cystic degeneration of uterine myoma should be considered as a differential diagnosis.展开更多
目的探讨磁共振扩散张量成像(DTI)在鉴别卵巢肿瘤和浆膜下子宫肌瘤中的价值。方法搜集MRI诊断为盆腔内子宫旁占位且经病理证实为卵巢肿瘤或浆膜下子宫肌瘤患者78例,根据病理结果和病灶实性成分T_2WI信号表现分为4组:A1组为T_2WI低信号...目的探讨磁共振扩散张量成像(DTI)在鉴别卵巢肿瘤和浆膜下子宫肌瘤中的价值。方法搜集MRI诊断为盆腔内子宫旁占位且经病理证实为卵巢肿瘤或浆膜下子宫肌瘤患者78例,根据病理结果和病灶实性成分T_2WI信号表现分为4组:A1组为T_2WI低信号的卵巢肿瘤12例,A2组为T_2WI高信号的卵巢肿瘤24例,B1组为T_2WI低信号的浆膜下肌瘤22例,B2组为T_2WI高信号的浆膜下肌瘤20例。4组患者均行1.5 T MRI常规序列、DWI及DTI序列扫描。由两名诊断医师独立测量各组病灶实性成分DWI的ADC值及DTI的D值、FA值。结果两名测量者测得的4组ADC、D、FA值一致性均很好(ICC值0.871~0.997)。A1组与B1组ADC、D、FA值差异均无统计学意义(P>0.05)。A2组ADC、D、FA值均低于B2组,差异均有统计学意义(P<0.05)。FA值对于A2组与B2组诊断效能很好,ROC曲线下面积为0.925。结论 DTI鉴别实性成分表现为T_2WI高信号的卵巢肿瘤与浆膜下子宫肌瘤有较高的价值,以DTI的FA值鉴别诊断效能最佳。展开更多
