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 analyze the CT features of primary ovarian cancer and ovarian metastases and their diagnostic and differential diagnosis. Methods 31 cases of ovarian primary malignant tumor and metastatic tumor confirmed by operation or pathology from 1999 to 2003 were retrospectively analyzed. The tumor location, internal density, septum, tumor wall, extracapsular neoplasm , Soft tissue components and ascites, peritoneum, omentum and lymph node metastasis. To compare the characteristics of primary ovarian cancer and ovarian metastases and the difference between the two. Results Twenty-four cases of ovarian primary malignant tumors were bilateral in 13 cases, including type Ⅱa in 3 cases, type Ⅱb in 11 cases, type Ⅱc in 7 cases and type Ⅲ in 3 cases. Ovarian metastasis type Ⅱ a in 6 cases; Ⅱ c in 1 case. Conclusion Primary ovarian cancer is more common in type Ⅱb and Ⅱc than in type Ⅱa. Metastases occur in the right side of the omentum, peritoneum and liver. Metastatic solid tumor was dendritic or silk-like changes to its characteristic changes.
