A 13-year-old girl was referred for assessment
of severe gastrointestinal tract bleeding. Her
liver function tests were normal, and she had no evidence
of chronic liver disease or history of significant
trauma. Clinical and sonographic findings suggested
the presence of a portal vein aneurysm associated
with a hepatoportal arteriovenous fistula. Abdominal
angiography confirmed the diagnosis. The arteriovenous
fistula was congenital, and the associated portal
vein aneurysm was either congenital or secondary
to hemodynamic changes in the portal venous system.
