摘　　要：目的通过64排CT来判断卵巢浆液性肿瘤的良恶性。方法经手术和病理证实的卵巢浆液性肿瘤58例,其中良、恶性肿瘤各25例,交界性肿瘤8例。全部行CT平扫和增强扫描,重点分析肿瘤强化特征和内部结构等。结果良性瘤灶以单房囊为主,囊壁及囊内未见强化或囊壁轻度强化(21/25例,84%),囊壁出现中度强化4例;恶性肿瘤呈囊实性,边界不清,形态不规则,分隔厚薄不均匀,可见壁结节,增强后实性部分明显强化(22/25例,88%),3例无明显强化。交界性肿瘤8例仅1例无强化,其余7例出现程度不等的强化。结论浆液性囊腺瘤多见于单囊且囊壁强化不明显,提示瘤灶缺乏血供或血供甚微;浆液性囊腺癌以混杂的囊实性为主,具有较明显的强化表现;交界性肿瘤强化程度略低于恶性瘤灶而但高于良性瘤灶。运用64排CT扫描有助于判断卵巢浆液性肿瘤的性质。Objective To assess the diagnostic value of contrast-enhanced 64-row CT scanning in deciding benign or malignant serous ovarian tumors. Methods Fifty-eight cases of serous ovarian tumors proved pathologically were reviewed, including 25 malignant tumors, 25 benign, 8 borderline tumors. All patients underwent 64-row CT scanning, including plain scanning and contrast-enhance scanning. The tumors＇ shape, density, blood supply and enhancement features were evaluated. Results Twenty-five cases of benign serous cystic adenoma were mostly unicameral, and showed a moderate mural enhancement only in 4 cases （16%） due to chronic pelvic infection and the otliers （21/25, 84%） had no or slight enhancement. Malignant tumors were cystic-solid mass with unclear margin, irregular shape and septa. Twenty-two cases of serous cystadenocarcinoma out of 25 cases （88%） appeared obvious enhancement and other 3 cases no enhancement. And 7 cases out of 8 （87.5%） borderlined serous cystadenomas showed different enhancement patterns. Conclusion Benign ovarian serous neoplasms were mostly unicameral and no strong mural enhancement, suggesting a lack of blood supply. While, there were obvious enhancement in the ovarian serous cystadenocarcinoma and borderline serous cystadenoma with malignant potential. The 64-row CT is helpful for differentiating the nature of the serous ovarian neoplasm.
