Seven examples of focal nodular hyperplasia of the liver have been demonstrated angiographically in 3 young women and 19-year-old girl. Six of these lesions were small and highly vascular, and appeared remarkably similar. One large solitary lesion was supplied by enlarged hepatic artery branches, contained a mass of abnormal, tortuous, irregular vessels and caused a dense, well-defined tumor stain. The angiographic differential diagnosis of these highly vascular, benign lesions is discussed and the radionuclide studies in these patients described.

Of 105 patients examined by liver scanning and celiac or hepatic angiography, a proved diagnosis was obtained in 77, with 26 cases of space-occupying masses and 35 cases of cirrhosis. The two techniques appear to be complementary to each other, although angiography usually provides more information and may show more and smaller intrahepatic lesions.
