Splenomegaly and variceal bleeding in a ten-year-old HIV-infected girl with noncirrhotic portal hypertension.

Noncirrhotic portal hypertension is an uncommon liver disease of unknown origin, increasingly described in HIV-infected adults. Prolonged antiretroviral exposure, in particular to didanosine, and thrombophilic predisposition have been suggested as potential pathogenic factors. Data are limited in children. We describe a 10-year-old HIV-infected girl with noncirrhotic portal hypertension who presented with progressive spleen enlargement and variceal bleeding.
