卵巢透明细胞癌的CT影像特征分析

目的探讨分析卵巢透明细胞癌的CT影像特征。方法回顾性分析12例有完整临床和CT图像资料并经病理证实的卵巢透明细胞癌,并总结其CT影像特征。结果 12例肿瘤发生的平均年龄约48岁,8例表现为I期病灶(75%);肿瘤均为单侧发生,平均最大径约11.6cm;肿块均呈囊性病灶伴发实性突起改变,单房囊实性10例,多房囊实性2例;9例病灶边缘清晰光整;囊性部分平均CT值约18HU;11例病灶实性突起呈偏心性附壁生长,6例病灶实性突起数目≤3个;增强后实性突起均呈明显不均匀强化。本组2例病灶伴发子宫内膜异位;5例病灶伴发腹水。结论卵巢透明细胞癌的CT表现具有一定的特征性,CT是诊断本病有价值的方法。

Analysis of the CT Imaging Features of Ovarian Clear Cell Carcinoma

Objective To investigate the CT imaging features of ovarian clear cell carcinoma.Methods 12 cases of ovarian clear cell carcinoma with complete clinical dates and CT images which confirmed by pathology were retrospectively analyzed, and the characteristics of CT were summarized.Results The average age of 12 cases was about 48 years old. 8 cases (75%) presented with stage-I disease. Tumors were unilateral in all the cases. The average maximum diameter of tumors was 11.6cm. All 12 cases showed cystic masses with solid protrusions. The cysts were unilocular in 10 lesions and multilocular in 2. 9 cases had smooth margin. Average CT value of the cystic portion was 18HU. The solid protrusions showed an eccentric pattern in 11 cases. The number of protrusions in 6 cases was≤3. The solid protrusions had obviously heterogeneous enhancements after contrast.2 cases were associated with endometriosis, and 5 cases were associated with ascites. Conclusion The CT features of ovarian clear cell carcinoma have certain characteristics and thus CT provides as a valuable diagnostic measure.
