| 目的 探讨卵巢黄体囊肿破裂（OCLCR）的MRI表现。方法 回顾性分析经手术病理证实的28例OCLCR的临床、MR影像资料。结果 28例附件区可见单囊、多囊或多房囊性包块，长径3.0～12.0 cm。根据肿块形态不同在MRI上分为3型：Ⅰ型为单囊型，17例，根据单囊与血肿位置不同又分为2种亚型，Ⅰa型（囊内血块型）8例，Ⅰb型（囊肿旁血肿型）9例；Ⅱ型为多囊型，5例；Ⅲ型为多房型，6例。增强扫描25例，囊壁及分隔厚约2.5～5.0 mm，呈环形、分隔状明显强化，20例囊壁见破裂口表现环形强化连续性中断、塌陷或缺损。与手术病理结果对照，MRI对OCLCR破裂口的诊断敏感度为90.91%（20/22）、特异度为100% （6/6），准确率为92.86%（26/28）。MRI与手术病理诊断的一致性高（Kappa=0.81，P<0.001）。结论 OCLCR MRI表现附件区单囊、多囊或多房厚壁囊肿，MRI能准确识别囊壁破裂口，与手术病理具有高度一致性。 |

| Objective To investigate the MRI manifestation of ovarian corpus luteum cyst rupture (OCLCR). Methods The clinical and MR image data of 28 OCLCR cases proved by pathology were analysed retrospectively. Results Single, multilocular or multilocular cystic masses were detected in the 28 cases, the length diameter varied from 3.0 cm to 12.0 cm. The lesions were devided into 3 types according to the shapes of cysts. TypeⅠ, single cyst (17 cases), and 8 cases detected blood clot in cyst (type Ⅰa), 9 cysts besides hematoma (type Ⅰb). Type Ⅱ, multiple cyst (5 cases), Type Ⅲ, multiocular cyst (6 cases). In the enhanced images, thickened cyst wall and septa were detected, varied from 2.5 mm to 5.0 mm. The rupture areas could be seen in 20 cases,showing peripheral interruption, failures or defects. Taking operation pathology as gold standard, the diagnostic sensitivity of OCLCR was 90.91% (20/22), specificity was 100% (6/6), and accuracity was 92.86% (26/28). The consistency between MRI and the operation pathology was high (Kappa=0.81, P<0.001). Conclusion MRI shows single cysts, multicysts or multilocular thick-walled cysts in OCLCR. MRI can accurately identify the rupture of the cyst wall and has high consistency with the operation. |
