摘要
目的 :探讨肝癌自发破裂出血的CT表现特点及螺旋CT肝双期扫描临床应用价值。方法 :回顾性分析了 9例自发破裂出血性肝癌的CT表现。其中 4例行螺旋CT肝双期扫描。结果 :肝癌自发破裂出血形态有五种类型 :①肿瘤内片状出血灶并腹腔内积血 ( 3例 )。②肝包膜下积血 ,肿瘤内无出血灶 ( 1例 )。③肿瘤内单发片状出血灶 ( 2例 )。④肿瘤内多发斑片状出血 ( 1例 )。⑤肿瘤边缘环状出血灶 ( 2例 )。 4例螺旋CT肝动脉期肿瘤内可见不规则斑点状、条状强化肿瘤血管及肿瘤组织 ,少量强化肿瘤血管纤细、僵硬且伸入出血灶内。 1例门静脉期肿瘤组织强化。 4例肿瘤出血灶内无强化及强化肿瘤血管 ,未见破裂肿瘤血管及造影剂外溢。结论 :CT检查是诊断肝癌破裂出血的有效方法 ,螺旋CT肝双期扫描可显示自发破裂出血性肝癌的血供情况 。
Objective:To discuss the CT feature of spontaneous rupture of primary hepatocellular carcinoma and clinic application value of hepatic dual-phases CT.Methods:The CT data of spontaneous rupture primary hepatocellular carcinoma(n=9) were reviewed retrospectively,four cases were examined by hepatic helical dual-phases CT scanning.Results:The hemorrhage shape of spontaneous rupture primary hepatocellular carcinoma was divided five types:①high-density blood of tumor with intraperitoneal hemorrhage (n=3).②single patch high-density blood in the tumor areas (n=2).③hemorrhage under hepatocapsule (n=1).④multiple spot?patch high-density blood in the tumor areas (n=1).⑤circular high-density blood in the peripheral areas of tumor (n=2).Enhanced tumor vessels or tissues were demonstrated during hepatic arterial-phase and few small and straight tumor vessels stretch into hemorrhage areas (n=4).Hemorrhage areas of tumor were not enhanced and demonstrated ruptured tumor vessels during hepatic dual-phase (n=4).Conclusion:CT is an effective method in diagnosis of spontaneous rupture hepatocellular carcinoma,hepatic helical dual-phases CT scanning could not demonstrate ruptured tumor vessels.
