肝癌自发性破裂出血的MRI诊断

MRI Diagnosis of Spontaneous Ruptured Hepatocellular Carcinoma

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 discuss the MR imaging features of spontaneous ruptured hepatocellular carcinoma（HCC）.Methods：The MRI findings of 6 ruptured HCC cases which were confirmed by surgery or digital subtraction angiography（DSA） were retrospec-tively analyzed.Results：All patients underwent plain and enhanced MR scanning,the liver subcapsular hemorrhage in 4 cases,intraperi-toneal bleeding in 2 cases.Hemorrhage shows higher or equal signal in T1 weight imaging and high or low signal in T2 weight imaging.The incomplete tumor capsule can be shown in 5 cases.Conclusion：The spontaneous ruptured HCC can be diagnosis through MR imag-ing timely and accurately.T1 weight imaging and coronal images in delayed scanning are significant to the diagnosis.
