【摘要】：目的探讨卵巢癌肝周转移的多层螺旋CT影像特点。方法回顾性分析63例卵巢癌患者的临床及影像学资料,术前或术后随访观察明确诊断肝脏转移瘤。观察分析肝脏及肝周转移灶的部位、密度及强化特点以及与邻近肝包膜的关系。结果 63例卵巢癌患者中,其中61例共155个肝脏转移瘤:肝内转移灶87个,肝周转移转移灶68个(24个病灶侵及肝实质,44个病灶未侵及肝实质)。2例呈肝内弥漫性转移(未纳入统计)。155个转移病灶:36个实性结节,20个囊实性结节,99个低密度影;2例转移性钙化,5例病灶周围异常高灌注。同期收集其他器官源性恶性病变肝脏转移瘤各30例(胃癌、结肠癌、肺癌、乳腺癌、胰腺癌),共822个肝脏转移灶,其中肝内765个,肝周55个,结果显示卵巢癌与其他器官来源肝转移瘤病灶分布之间的差异具有统计学意义(X~2=166.9,P=0.0000.05)。结论卵巢癌肝脏转移瘤的肝周分布是其重要影像特征。
[Abstract]:Objective to investigate the features of multislice spiral CT in perihepatic metastasis of ovarian cancer.Methods the clinical and imaging data of 63 patients with ovarian cancer were retrospectively analyzed.The location, density and enhancement of hepatic and perihepatic metastases were observed and analyzed.Results Sixty-one of 63 patients with ovarian cancer had 155 liver metastases, including 87 intrahepatic metastases.There were 68 metastatic foci (24 lesions involving hepatic parenchyma, 44 lesions without invasion of hepatic parenchyma). 2 cases showed diffuse intrahepatic metastasis (not included. 155 metastases: 36 solid nodules, 20 solid cystic nodules, 99 hypodense nodules)There were 5 cases of metastatic calcification and 5 cases of abnormal hyperperfusion around the lesion.A total of 822 liver metastases were collected from 30 patients with other organogenic malignant lesions (gastric cancer, colon cancer, lung cancer, breast cancer and pancreatic cancer), including 765 in the liver and 55 in the perihepatic region.The results showed that there was a statistically significant difference in the distribution of lesions between ovarian cancer and other organ derived liver metastases.Conclusion the perihepatic distribution of hepatic metastases of ovarian cancer is an important imaging feature.
