Focal Nodular Hyperplasia of the Liver

Abstract

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.
