CT诊断卵巢子宫内膜样癌

CT diagnosis of ovarian endometrioid carcinoma

目的探讨卵巢子宫内膜样癌的CT特点并评价其诊断价值。方法回顾性分析23例经手术病理证实的卵巢子宫内膜样癌的术前CT表现。结果 23例中,7例合并子宫内膜异位症及子宫腺肌症,1例合并子宫内膜单纯增生,5例合并子宫内膜癌。肿瘤表现为圆形、卵圆形或分叶状的囊实性或实性病变,囊内分隔厚薄不均,伴有囊壁及结节样、乳头样及片状不规则实性区。增强后肿物实性部分强化不均匀,强化程度等或略高于肌肉。结论卵巢子宫内膜样癌的CT表现具有一定特征性,可辅助诊断,但最终确诊仍需结合临床并依赖于病理学检查。

Objective To explore the diagnostic value of CT for ovarian endometrioid carcinoma. Methods CT findings in 23 patients with ovarian endometrioid carcinoma confirmed by surgery and pathology were analyzed retrospectively. Re- sults Among 23 patients, associated endometriosis and adenomyosis were found in 7 cases, endometrial hyperplasia in one case, endometrial cancer in 5 cases. The lesions were round, oval, lobulated cystic-solid or solid formation with thick or thin septa, nodule, papilla and irregular solid regions. Heterogeneous enhancement was observed, which was equivalent or slightly higher than the muscles. Conclusion CT characteristics can aid in diagnosis of ovarian endometrioid carcinoma, while definite diagnosis relies on combination of clinical features and pathology examination.
