摘　　要：目的分析原发性卵巢恶性肿瘤与卵巢转移瘤的CT影像学特征及其诊断与鉴别诊断.方法回顾分析自1999-04～2003-11的31例经手术或病理证实的卵巢原发恶性肿瘤和转移瘤的CT影像表现,重点观察肿瘤部位、内部密度、分隔、瘤壁、囊内外赘生物、软组织成分以及腹水,腹膜、网膜种植及淋巴结转移.比较原发性卵巢恶性肿瘤与卵巢转移瘤各自特点及两者之间的鉴别点.结果 24例卵巢原发恶性肿瘤中双侧占13例,其中Ⅱa型3例;Ⅱb型11例;Ⅱc型7例;Ⅲ型3例.卵巢转移瘤Ⅱa型6例;Ⅱc型1例.结论原发性卵巢恶性肿瘤以Ⅱb及Ⅱc型多见,转移瘤以Ⅱa型多见.转移灶好发于右侧网膜、腹膜及肝脏.转移瘤肿瘤实性部分呈树枝状或丝网状改变为其特征性改变.Objective To analyses the CT characteristics of primary malignant ovarian tumors and metastatic ovarian carcinoma and its diagnosis and differential diagnosis.Methods CT findings in 31 patients with pathologically-proved malignant ovarian tumors,encountered during 1999-04~2003-11 were retrospectively analyzed.The observation of the lesion was focused on the following aspects:location,internal density,septa,wall,intra-cystic and extra-cystic vegetation,the composition of the soft tissue,ascites,peritoneum,mental implantation and metastatic lymphadenopathy.The characteristic of each in both primary malignant ovarian tumor and metastatic ovarian tumor were compared.Results Among the 24 primary malignant ovarian tumors,13 patients had lesions in both sides of ovary,type Ⅱa:n=3,Type Ⅱb:n=11,Type Ⅱc:n=7,Type Ⅲ:n=3.Among the metastatic ovarian carcinomas,Type Ⅱa:n=6,Type Ⅱc:n=1.Conclusion Type Ⅱb and Ⅱc are commonly seen in primary malignant ovarian tumors.Type Ⅱa is always seen in metastatic ovarian carcinoma.The metastatic tumors often happen in the right peritoneum,epiploon,and liver.'arborization and silk screen likely'are the characteristic representation of the metastatic ovarian carcinoma.
