目的：探讨卵巢透明细胞癌的CT影像学特征。方法：由2名有经验的放射诊断医师回顾分析经手术病理证实的11例卵巢透明细胞癌的影像学资料，总结影像学特征(位置、大小、边缘、囊实性、囊性部分CT值、实性部分CT值、强化程度、腹腔积液、腹膜转移和淋巴结转移情况)。结果：10例为单侧发生，1例双侧。9例表现为囊实混合型肿块，2例为实性型肿块。最长径10.5~22.5 cm，平均16.1 cm。囊实混合型肿块囊性部分CT值11~55 HU，中位值18 HU。肿块内均可见不规则乳头状结节或团块样实性成分；实性部分CT值34~49 HU；增强各期中动脉期CT值46~57 HU，静脉期CT值56~66 HU。2例实性型肿块CT值分别为39、46 HU。5例伴有腹腔积液，3例腹膜不规则絮状或结节状增厚，未见淋巴结肿大。结论：卵巢透明细胞癌的CT表现为巨大囊实混合型或实性型肿块，多为单发。肿块内含有较高密度液性成分、乳头状突起和实性结构，轻中度强化。
目的：探討卵巢透明細胞癌的CT影像學特徵。方法：由2名有經驗的放射診斷醫師迴顧分析經手術病理證實的11例卵巢透明細胞癌的影像學資料，總結影像學特徵(位置、大小、邊緣、囊實性、囊性部分CT值、實性部分CT值、彊化程度、腹腔積液、腹膜轉移和淋巴結轉移情況)。結果：10例為單側髮生，1例雙側。9例錶現為囊實混閤型腫塊，2例為實性型腫塊。最長徑10.5~22.5 cm，平均16.1 cm。囊實混閤型腫塊囊性部分CT值11~55 HU，中位值18 HU。腫塊內均可見不規則乳頭狀結節或糰塊樣實性成分；實性部分CT值34~49 HU；增彊各期中動脈期CT值46~57 HU，靜脈期CT值56~66 HU。2例實性型腫塊CT值分彆為39、46 HU。5例伴有腹腔積液，3例腹膜不規則絮狀或結節狀增厚，未見淋巴結腫大。結論：卵巢透明細胞癌的CT錶現為巨大囊實混閤型或實性型腫塊，多為單髮。腫塊內含有較高密度液性成分、乳頭狀突起和實性結構，輕中度彊化。

Objective: To evaluate the imaging features of CT in patients with pathologically proved ovarian clear cell carcinoma (CCC). Methods:The CT imaging ifndings of 11 patients with histopathologically proven ovarian CCC were retrospectively analyzed by two radiologists in consensus. The imaging features were evaluated including the location, size, margin, mass characteristic, attenuation of cystic and solid portions, and presence of protruding mass into the lumen, etc. Results:The lesions were located unilaterally in ten patients and bilaterally in one patient. Nine lesions showed mixed appearance of cystic and solid nodules, and two lesions were solid masses. The average size of the tumors was 16.1 cm (ranging from 10.5 cm to 22.5 cm). The average CT attenuation of the cystic portion was 18 HU (ranging from 11 to 55 HU). Protruding masses appeared in nine lesions with enhancement. The CT attenuation value of solid portion was 34 to 49 HU on plain scan, 46 to 57 HU in the arterial phase, and 56 to 66 HU in the venous phase. The CT attenuation valu was 39 HU and 46 HU in two solid masses. 5 cases had abdominal cavity effusion and 3 cases had peritoneal irregular flocculent or nodular thickening without lymph node enlargement. Conclusion:On CT imaging the ovarian CCC is shown as large unilocular, mainly cystic and smooth marginated mass with protruding solid portion into the lumen and high-attenuated cystic portion.
