Abstract

The angiographic findings in hydatid cysts, non-parasitic cysts, abscesses, multiple nodular hyperplasia, cavernous haemangioma, adenoma and focal nodular hyperplasia of the liver are described. The presence of a thin rim of parenchymal opacification around a cystic lesion indicates that the lesion is under tension and is probably increasing in size. This sign is not present with hydatid cysts which are ruptured, secondarily infected or calcified. Multiple nodular hyperplasia is the commonest cause of an avascular mass in a cirrhotic liver and diagnosis rests on the lack of correlation of the findings at angiography and liver scanning. Cavernous haemangiomas produce characteristic appearances. An arrangement of arteries feeding liver cell adenomas is described which may be characteristic of these lesions. Focal nodular hyperplasia also appears highly vascular on angiography. The complementary role of angiography and scanning in many of these lesions is illustrated.
