Metastasis to the appendix from a hepatocellular carcinoma manifesting as acute appendicitis: CT findings.
Metastasis to the appendix is extremely rare. Moreover, metastasis from a hepatocellular carcinoma (HCC) has not been reported in the English language literature. We report a case of metastasis to the appendix from a HCC in a 50-year-old man who presented with pain in the right lower quadrant of the abdomen, representing acute appendicitis. On CT, a hypervascular mass occupying the lumen of the appendix with distension of the appendiceal tip and surrounding peritoneal seeding of the HCC were observed. This is the first report of CT findings of metastasis to the appendix from a HCC.
