Direct communication between portal branches and the hepatic vein [macroscopic intra-hepatic portal-hepatic venous shunt (IPHVS)] is a rare entity. We have recently studied five patients with this condition. Magnetic resonance imaging (MRI) clearly demonstrated in each case the portal-hepatic venous shunt due to "flow void." Multiple diffuse shunts were present in one case and a solitary shunt was demonstrated in the others. The solitary shunt was either tubular, focally dilated or racemose in configuration. The MRI findings and clinical significance of this rare entity are discussed.
门静脉分支与肝静脉之间的直接沟通[宏观肝内门静脉-肝静脉分流（IPHVS）]是一种罕见的情况。我们最近研究了5例患有这种病症的患者。磁共振成像（MRI）在每个病例中都通过“血流空信号”清楚地显示了门静脉-肝静脉分流。1例存在多个弥漫性分流，其他病例显示为单一分流。单一分流的形态要么呈管状、局灶性扩张，要么呈葡萄状。本文讨论了这种罕见情况的MRI表现及临床意义。
