摘　　要：目的探讨卵巢卵泡膜细胞瘤的CT特点,提高对本病的CT诊断水平。方法分析7例经手术病理证实的卵巢卵泡膜细胞瘤患者的临床资料和CT表现。结果7例中肿瘤位于右侧附件区5例,左侧附件区2例。6例(6/7)表现为边界清楚的圆形、卵圆形实质性肿块,1例表现为边界清楚的分叶状实质性肿块,密度均与子宫肌层相近,病灶与子宫和肠腔分界清晰,5例肿瘤内可见散在小片状低密度区;增强扫描示肿瘤在实质期和延迟期呈缓慢渐进性轻度强化,5例肿瘤较大,其内散在小片状低密度区未见强化。7例中合并腹水6例,合并囊腺瘤、单发子宫肌瘤、多发子宫肌瘤各1例。结论卵泡膜细胞瘤的CT表现有一定特征性,CT对本病的诊断和鉴别诊断有重要价值。Objective：To study the CT characteristics of ovarian thecoma in order to improve the diagnostic accuracy. Methods：CT features of 7 patients with pathology proved ovarian thecoma were retrospectively analyzed. Results： The tumors were solid with some small patchy low attenuated areas （n= 5） ; located at right adnexa （n= 5）, left adnexa （n= 2） ; well-defined;round or oval （n=6） and lobulated （n= 1） in shape. The attenuation of tumor were close to that of uterus on plain CT. Distinct delineation could be assessed between the tumor and uterus as well as intestine. After contrast administration,gradual and mild enhancement could be revealed in the parenchymal phase and delay phase. For the 5 cases with large tumor,there were patchy areas with no enhancement. Of the 7 cases with ovarian thecoma, associated ascitis （n= 7）, cysxoadenoma, solitary and multiple uterine leiomyoma （n= 1 for each） were demonstrated. Conclusionz：CT characteristics were helpful in the diagnosis and differential diagnosis of ovarian thecoma.
