Abstract
We performed laparoscopic hepatic resection for focal nodular hyperplasia (FNH) diagnosed in a 7-year-old girl. The child was referred to our hospital because of an incidentally detected abdominal tumor by abdominal palpation. Abdominal enhanced CT revealed a 75 × 70 mm tumor contiguous with liver segment 5/6, with a central scar and a hepatic artery branch (A5) arising from the central scar. Based on these findings and the findings of further examinations by MRI and sonazoid US, the tumor was diagnosed as FNH. In consideration of the risks of bleeding, infarction and infection of the tumor, laparoscopic partial hepatectomy was performed. The histological diagnosis was FNH with proliferative bile ductules and an abnormal muscular artery in the central scar. The patient was discharged from the hospital 6 days after the surgery ; until now, 2 years 9 months since the surgery, there has been no evidence of recurrence.
