Doughnut-like hyperintense nodules on hepatobiliary phase without arterial-phase hyperenhancement in cirrhotic liver: imaging and clinicopathological features.

• HBP-doughnut nodules without APHE were seen in 6% of patients with liver cirrhosis. • The enhancement peak of HBP-doughnut nodules without APHE was in the portal phase, which reflected the fact that they were supplied predominantly by the portal vein, based on angiography-assisted CT findings. • None of the HBP-doughnut nodules without APHE in cirrhotic liver became malignant, and in conjunction with limited pathological features, they may be corresponding to multiacinar cirrhotic nodules in the International Working Party classification.
