Focal nodular hyperplasia of the liver in a child

We present a case of focal nodular hyperplasia (FNH) of the liver in a 7-ye ar-old girl. The hepatic tumor was found incidentally on physical examinati on at school. During surgery, a hypervascular mass with a nodular surface w as found to be confined to thr right lobe of the liver (mainly in segments 5 and 6). The brownish tumor and the gallbladder were completely removed; P athologic examination revealed a 10 x 9 x 5-cm mass with a central scar and radiating septa. consistent with the diagnosis of FNH. The postoperative c ourse was complicated by subhepatic effusion, which was resolved by percuta neous computed tomography-guided drainage. She remained well 2 years after surgery.
