摘　　要：目的　提高卵巢恶性肿瘤的CT诊断水平。方法　回顾性分析经手术及病理证实的 42例 ( 4 9个病灶 )卵巢恶性肿瘤CT检查结果 ,着重讨论了其CT表现及分型 ,CT鉴别诊断。结果　 ( 1)病灶多分布于附件区及子宫直肠窝区 ( 78.6 %)。 ( 2 )病灶多大于5cm( 95 .2 %)。 ( 3)病灶多有分叶表现 ( 71.4%)。 ( 4 )病灶表现为囊实型、实质型、囊肿型 ,以囊实型多见 ( 6 1.9%)。 ( 5 )实性病灶及病灶的实性部分有较明显强化 ( 90 .8%)。 ( 6 )转移表现多为腹水及邻近器官结构受侵。 ( 7)实性病灶及病灶的实性部分可有弧形、点状、结节状钙化。结论　CT扫描对卵巢恶性肿瘤的诊断及病理特征的显示有重要价值。Objective To improve the CT diagnostic rate of malignant ovarian tumor(MOT).Methods The CT appearences of 42 cases with MOT confirmed by operation and pathology were analyzed retropectively.The CT findings and types,differential diagnosis were emphatically discussed.Results (1)Ovanian tumors were most frequently located in the adnexal and the pouch of Douglas(78.6%);(2)The size of tumors was mostly beyond 5 cm in diameter(95.2%);(3)The most of tumors apperared flower-shaped(71.4%);(4)The tumors were classified as cystic,cyst-solid and solid types,but cyst-solid type was common(61.9%);(5)The solid and solid portion of the mass were enhanced obviously(90.8%);(6)Ascites and invasion of the adjacent organs were common appearences of the metastasis;(7)Arched,small nodelar and nodular calcification in a solid mass or solid portion of mass could be found.Conclusion CT examination is of great value in diagnosis of MOT,which may predict the pathologic characteristics of MOT.
