| 目的 探讨卵巢子宫内膜样癌（OEC）的CT和MRI表现。方法 回顾性分析经手术病理证实的21例OEC患者的CT或MRI及临床和病理学资料，分析其影像学和临床特点。结果 21例OEC患者共26个病灶，其中单侧16例，双侧5例，伴子宫内膜癌9例。26个病灶均呈囊实性，其中9个（9/26，34.62%）呈囊内结节型，17个（17/26，65.38%）呈囊壁增厚型，实性部分平扫CT值24~50 HU，MR平扫T1WI呈低信号，T2WI呈等或稍高信号，DWI呈高信号，ADC图呈低信号；13个病灶囊内液呈水样改变，4个呈巧克力囊肿样改变；增强扫描实性部分明显强化，其中11个（11/17，64.71%）病灶呈“梳状”强化。伴和不伴子宫内膜癌OEC的病灶大小、形态及影像表现特征差异均无统计学意义（P均>0.05）。结论 OEC在CT、MR表现有一定的特异性，有助于术前定性诊断。 |

| Objective To study the CT and MRI features of ovarian endometrioid carcinoma (OEC). Methods A total of 21 OEC patients proved by surgery and pathology were enrolled. The CT or MRI findings and clinical data were analyzed retrospectively. Results Totally 26 lesions were detected in 21 cases, 16 cases were unilateral and 5 cases were bilateral. Nine patients accompanied with uterine endometrioid carcinoma. All of the lesions were mixed cystic-solid, the solid components presented "nodular in cyst" in 9 lesions (9/26, 34.62%), while "cystic wall thickening" pattern in 17 lesions (17/26, 65.38%) was observed. The CT value of solid parts were 24—50 HU. The solid parts were low signal intensity on T1WI, iso or slightly high signal intensity on T2WI, high signal intensity on DWI with low signal intensity on ADC maps. The cystic components showed water like signal in 13 lesions, endometriosis cyst like signal in 4 lesions. Obviously enhancement were seen in solid parts in all lesions, in which 11 lesions (11/17, 64.71%) showed "comb shape" enhancement. There were no statistically differences in size, morphology and imaging manifestations of OEC with or without uterine endometrioid carcinoma (all P>0.05). Conclusion CT and MR imaging demonstrate some morphological features of OEC, which is helpful to correct diagnosis preoperatively. |
