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 diagnosis of ovarian cancer. Methods The CT findings of 42 cases (49 lesions) of ovarian malignant tumors confirmed by operation and pathology were retrospectively analyzed. The CT findings and classification and CT differential diagnosis were mainly discussed. Results (1) The lesions were mostly distributed in the accessory area and the uterine rectum (78.6%). (2) The lesions were more than 5cm (95.2%). (3) lobulation more lesions (71.4%). (4) The lesions showed cystic solid type, parenchymal type, cystic type, and cystic type more common (6 1.9%). (5) The real part of the lesion and solid lesions were more obviously enhanced (90.8%). (6) Most of metastasis showed ascites and adjacent organs structure invasion. (7) Solid lesions and solid lesions may have the actual part of the arc, punctate, nodular calcification. Conclusion CT scan has important value in diagnosis and pathological features of ovarian cancer.
