转移性卵巢肿瘤的CT诊断

CT Diagnosis of Ovarian Metastatic Tumors

目的 评价转移性卵巢肿瘤的CT诊断价值。资料与方法 对 2 9例经手术病理证实的转移性卵巢肿瘤进行CT回顾性分析。结果 2 9例转移性卵巢肿瘤CT发现 45个肿瘤 ,18例为双侧病灶 (6 2 .1%) ,9例为单侧病灶(31.0 %) ,2例未发现病灶 ;45个肿瘤中Ⅰ型 3个 ,Ⅱa型 14个 ,Ⅱb型 10个 ,Ⅱc型 11个 ,Ⅲ型 7个 ;以囊性为主的病灶 17个 ,占 37.8%,混合性 10个 ,占 2 2 .2 %,实性为主的病灶 18个 ,占 40 .0 %;以囊性为主的病灶单房 3个 ,多房14个 ;原发部位分别为胃 10例 ,肠 7例 ,原发部位不明 5例 ,宫颈 2例 ,乳房、胆囊、阑尾、肺及类癌各 1例。结论 转移性卵巢肿瘤病灶以双侧多见 ,实性为主 ,原发灶常见于胃肠道。

Objective To evaluate CT scanning in diagnosing ovarian metastases.Materials and Methods CT findings in 29 patients with pathologically-proved ovarian metastases were retrospectively analyzed.Results A total of 45 lesions were found on CT scans in 29 cases. Of 29 cases, the lesions were bilateral in 18 (62.1%) and unilateral in 9 (31%), no lesions were found in the remaining two. Of the 45 lesions, type Ⅰ had 3, type Ⅱa 14, type Ⅱb 10, type Ⅱc 11 and type Ⅲ 7. The lesions were mainly cystic in 17 (37.8%), mixed in 10 (22.2%), solid in 18 (40.0%). Of the 17 cystic lesions, 3 were unilocular while 14 multilocular. The primary neoplasms included stomach (n=10), intestine (n=7), uterine cervix (n=2), breast (n=1), gallbladder (n=1), appendix (n=1), lung (n=1), carcinoid (n=1) and unknow (n=5).Conclusion Most ovarian metastases are bilateral and solid. The primary lesions are mainly in the gastrointestinal tract.
