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

ConclusionHBP-doughnut nodules without APHE in cirrhotic liver were not infrequent. None became malignant. We propose calling them ‘multiacinar cirrhotic nodules’ based on the classification by an International Working Party.Key Points• 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.
