title: Focal nodular hyperplasia of the liver in children: a report of three new cases.
abstract: Three cases of focal nodular hyperplasia of the liver in children are presented. The angiographic findings of a hypervascular mass with dense, delayed capillary stain in combination with increased uptake of 99mTc sulfur colloid on radionuclide scans were present in two cases. Computed tomography, utilized in one case, demonstrated a well-circumscribed mass with an irregular stellate area of low density which corresponded to the central collagenous scar described pathologically. The ultrasonographic finding was that of a mass slightly less echogenic than surrounding normal liver tissue.
