Nodular transformation of the liver in hereditary hemorrhagic telangiectasia

A case of hereditary hemorrhagic telangiectasia with prominent nodular transformation of the liver is described. The presence of enlarged arteries was documented morphometrically. Artery-to-portal vein shunts were also found. The association of abnormal vessels with hepatic nodules supports the hypothesis that abnormalities of blood flow cause nodular transformation. Nodular transformation may be the lesion that has heretofore been termed cirrhosis hepatis telangiectasia or atypical cirrhosis.
