title: Hepatocellular carcinoma with ring calcification: report of two cases.
abstract: Two cases of hepatocellular carcinoma (HCC) with ring calcification are reported together with their CT findings. HCC in both cases showed little early enhancement followed by delayed enhancement on dynamic CT. The pathologic specimen in one case showed HCC with fairly abundant fibrosis, and calcification was noted underneath the thick fibrous capsule, which might explain the enhancement pattern on CT.
