Background. - Hepatoportal sclerosis is uncommon in European countries
and its diagnosis is difficult. The etiology remains unknown; its fam
ilial origin is probably exceptional. Case report. - An 18-month-old g
irl born to a mother with hepatoportal sclerosis had hepatomegaly. She
also had a moderate splenomegaly and mild increase transaminase and g
amma GT activities. Ultrasound examination failed to show portal hyper
tension. Histological study of liver showed changes quite similar to t
hose seen in her mother. Two members of the mother's family had portal
hypertension. Discussion. - Familial forms of portal hypertension hav
e been reported: a familial form of incomplete septal cirrhosis and a
familial occurrence of cavernous transformation of the portal vein. Ob
struction of the portal vessels was not found in our patient, the youn
gest in whom hepatoportal sclerosis is documented.
