Nodular regenerative hyperplasia of the liver in children.
Sixteen cases of nodular regenerative hyperplasia of the liver in children are presented. The patients, 10 girls and 6 boys, were between the ages of 7 months and 13 years, with a median of 6 years. Clinically, nine children presented with hepatomegaly or splenomegaly, with and without signs of portal hypertension. A history of anticonvulsant drug therapy was obtained in four patients. Associated conditions in the remaining three cases were Donohue's syndrome, disseminated intravascular coagulation, and angiomyolipoma of the kidney. In five patients a clinical diagnosis of primary intra-abdominal tumor was made. Follow-up showed that six patients died of causes unrelated to the nodular hyperplasia. Two patients were asymptomatic when last seen 5 and 18 years after the initial diagnosis of nodular hyperplasia. Both patients underwent shunt surgery. No follow-up was available for eight patients. The importance of recognizing this entity in the pediatric age group, as well as its histopathologic differential diagnosis, is stressed.
