Budd-Chiari综合征的CT、MRI诊断价值

目的分析布-加氏综合征的MR、ICT的表现,进一步提高该病的诊断率。方法对经血管造影证实的15例Budd-Chiari综合征的MR、ICT表现进行回顾性分析。结果15例MRI和CT诊断均正确,2例伴多发再生结节定性诊断正确。Budd-Chiari综合征MR、CT有下列征象:(1)下腔静脉和/或肝静脉狭窄或闭塞(15例);(2)肝实质淤血肿胀伴异常密度或信号灶(12例),延迟扫描无明显强化(7例),部分可见肝实质强化逐渐均匀(5例);(3)迂曲增粗及逗点状侧枝循环(10例);(4)无肝炎背景的肝硬化、腹水,伴或不伴脾轻度肿大(4例),伴侧枝循环形成(15例);(5)多发再生结节(2例)。结论MRI、CT对Budd-Chiari综合征的诊断具有重要价值。

CT and MR Imaging Diagnosis of Budd-Chiari Syndrome

Objective To analyse MR imaging and CT findings of Budd-Chiari syndrome,so as to improve the diagnosis of it.Methods MR imaging and CT findings of 15 cases of Budd-Chiari syndrome were analysed retrospectively.Results All 15 cases were correctly diagnosed by MRI and CT,and 2 cases accompanied multiple regenerative nodi were also diagnosed correctly.The signs of Budd-Chiari syndrome on CT and MRI included:(1) inferior vena and/or hepatic vein stenosis or occlusion(15 cases);(2) liver parenchyma congestion with abnormal signal intensity or density(12 cases),no enhancement(7cases)or gradually enhancement(5 cases);(3) circuity thickening or comma sign of collateral circulation(10 cases);(4) liver cirrhosis without hepatitis background,ascitic fluid,with or without spleen swell lightly(4 cases),collateral circulation formed(15 cases);(5) multiple regenerative nodules(2 cases).Conclusion CT and MRI have important value in diagnosing Budd-Chari syndrome.
