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=0.000<0.05)。结论卵巢癌肝脏转移瘤的肝周分布是其重要影像特征。
Objective To explore the CT characteristics of peripheral hepatic metastasis from ovarian cancer discuss MDCT features of peripheral hepatic metastasis from ovarian carcinomas. Methods The clinical and radiological data of 63 patients with ovarian cancer were retrospectively analyzed and the preoperative or postoperative follow - up study were conducted in order to clearly determine the diagnosis of liver metastases. The liver morphology and the lesion in terms of location of peripheral liver metastases, density, strengthening characteristics, and the relationship with the adjacent liver capsule were observed and analyzed. Results Among those 63 patients with varian cancer, a total of 155 foci of liver metastases were detected in 61 cases, in which liver metastases were found in 87, hepatic subcapsular metastases in 43, perihepatic peritoneum metastases in 21, liver capsule metastasis in 4, perihepatic metastases in 68, including 24 lesions that invaded the liver parenchymal invasion and 44 did not. 2 cases showed diffuse liver metastasis, which were not included in the statistics. 155 metastatic lesions were comprised of 36 solid nodules, 20 cystic or solid nodules, 99 low density shadows, 2 metastatic calcifications, 5 hepatic perfusion disorders. At the same period, 30 cases of the other organs borne liver metastases of malignant lesions, （stomach, colon, lung, breast, pancreatic cancer were collected, with a total of 822 liver metastases, of which 765 were in liver and 55 were perihepatic metastases. Statistic analysis showed that the lesion distribution in liver metastases from ovary cancer were significant difference from the other organs （ χ^2= 166.9, P = 0. 000 〈 0.05 ）. Conclusion Peripheral distribution of hepatic metastasis from ovarian cancer is an important image features.
