目的:探讨肝癌自发性破裂出血的MRI图像特征。方法:对6例经手术或肝动脉血管造影确诊为原发性肝癌破裂出血患者的MR图像进行回顾性分析,总结其临床特点及MRI图像特征。结果:6例患者均行MR平扫及增强扫描,肝被膜下出血4例,腹腔内出血2例。出血表现为T1WI呈高或等信号,T2WI呈高或低信号,5例可清晰显示肿瘤破口。结论:MR诊断肝癌自发性破裂出血及时、准确,T1WI及延迟扫描冠状位图像对诊断有定性意义。
Objective: To investigate the MRI features of spontaneous rupture of liver cancer. Methods: Six patients with primary hepatic carcinoma rupture hemorrhage diagnosed by operation or hepatic arteriography were retrospectively analyzed. The clinical features and MRI features were summarized. Results: All the 6 patients underwent MR plain scan and enhanced scan. There were 4 cases of subhepatic hemorrhage and 2 cases of intraperitoneal hemorrhage. Hemorrhage showed T1WI was high or equal signal, T2WI was high or low signal, 5 cases can clearly show the tumor break. Conclusion: The diagnosis of spontaneous rupture of hepatocellular carcinoma by MR is timely and accurate. The T1WI and delayed-scan coronal images have certain significance for the diagnosis.
