PV-CTA shows that the trunk and branches of PV are absent, the SV is widened, with the SMV joining the LRV and then draining directly into the IVC without passing through the liver (a). CTA also reveals the enlargement of the spleen and splenic veins (arrows) and heterogeneous density lesions in the liver nodules (arrows) (b). PV: portal vein; CTA: computed tomography angiography; SV: splenic vein; SMV: superior mesenteric vein; LRV: left renal vein; IVC: inferior vena cava
