Arterioportal fistulae (APFs) are rare. An asymptomatic APF was suspected by computed tomography. Multiplanar, maximum intensity projection, and surface shaded display reconstructions showed its anatomy. To our knowledge, this is the first report using such reconstructions to analyze the architecture of an extrahepatic APF. Complete assessment of APF can be achieved noninvasively, and initial endovascular treatment can be planned.
