[Focal nodular hyperplasia of the liver--is a radiologic diagnosis possible? (author's transl)].

Focal nodular hyperplasia of the liver (FNH) is a histologically defined benign tumor, which can be distinguished from other space-occupying diseases of the liver. The present paper deals with the question whether FNH can be distinguished from other lesions of the liver by a combination of radiologic procedures. Therefore 10 patients with FNH of the liver underwent sonography, hepatic scintigraphy, computed tomography with dynamic CT--densitometry, and angiography. The computed tomography with dynamic CT--densitometry using intravenous bolus injection of contrast medium seems to be the most accurate method for detection of FNH of the liver.
