A 13-year-old girl was referred for assess-ment of severe gastrointestinal tract bleeding. Herliver function tests were normal, and she had no evi-dence of chronic liver disease or history of significanttrauma. Clinical and sonographic findings suggestedthe presence of a portal vein aneurysm associatedwith a hepatoportal arteriovenous fistula. Abdominalangiography confirmed the diagnosis.
