摘　　要：目的探讨螺旋CT双期增强扫描对卵巢囊腺癌的诊断价值。方法回顾性分析31例经手术病理证实为卵巢囊腺癌(瘤)的螺旋CT双期增强表现,对肿瘤进行定位、定性分析,重点观察肿瘤部位、内部密度、分隔、瘤壁、软组织成分以及腹水、腹膜、网膜种植及淋巴结转移的影像特点,从而达到诊断与鉴别诊断。结果病灶多分布于附件区及子宫直肠窝区(77.3%);病灶多大>5cm(93.5%);病灶表现为囊肿型(Ⅰ型)、囊实型(Ⅱ型)、实质型(Ⅲ型),以囊实型多见(60%),囊实型又分为Ⅱa、Ⅱb、Ⅱc3个亚型;转移多表现为腹水及腹膜、网膜种植。结论卵巢囊腺癌(瘤)最常见的类型为Ⅰ、Ⅱ型。良性肿瘤以Ⅰ型常见,恶性肿瘤以Ⅱ型常见。螺旋CT双期增强扫描对卵巢囊腺癌的诊断有很高的价值。Objective To evaluate the diagnosis of ovarian cystadenocarcinoma by dual-phase contrast enhanced spiral CT. Methods The dual-phase contrast enhanced the spiral CT results of 31 cases of ovarian cystadenocarcinoma(cystadenoma), which were confirmed by operation and pathology, were analyzed retrospectively. The location and characterization of the carcinoma were analyzed. The analysis was focus on the location, internal density, septa, wall, the composition of the soft tissue, ascites, peritonium, omental implantation and metastasis lymphadenopathy imaging features. Results Ovarian cystadenocarcinoma (cystadenoma) were most frequently located in the adnexal and the pouch of Douglas (77.3%).The size of tumors was mosdy beyond 5 cm in diameter(93.5%).The tumors were classified as cystic (type Ⅰ) ,cyst-solid (type Ⅱ) and solid types (type Ⅲ), in which cyst-solid type was common (60%) and was further classified into three type(Ⅱ a, Ⅱ b and Ⅱ c). Ascites, peritoneum and omental implantation were the common forms of the metastasis. Conclusions Type Ⅰ and Ⅱ ovarian cystadenocarcinoma are commonly seen. The benign tumors often present as type Ⅰ , while the malignant ones often present as type Ⅱ . Dual-phase contrast enhanced spiral CT has high value for diagnosis of ovarian cystadenocarcinoma.
