Abstract:
Objective To analyze the multi-slice spiral CT(MSCT) angiographic features of hepatic hemangioma accompanied with peripheral arterial-portal shunt(APS),and to assess the MSCT diagnostic ability and clinical value for peripheral APS.Methods 12 cases of hepatic hemangioma accompanied by peripheral APS underwent triphase enhanced MSCT scan,the images were post-processed with maximum intensity projection(MIP),volume rendering(VR) and then analysed.Results During hepatic arterial phase,the peripheral APS and transient hepatic parenchymal enhancement(THPE) could be visualized on MIP and VR.APS were classified into four types according to the findings on VR and MIP.TypeⅠ: Branch of the portal veins early enhancement in peritumoral wedge-shaped enhanced area,more frequently appeared as parellel track sign;TypeⅡ: Showed early opacification of small portal branchs near tumors,APS more frequently found in peritumoral wedge-shaped enhanced area;Type Ⅲ:Included both typeⅠand typeⅡ signs;Type Ⅳ: Only showed peritumoral THPE.Conclusion MSCT angiography provides a new effective technique for demonstrating and understanding peripheral APS and THPE.
