A 17-year-old girl known to suffer from essential thrombocytosis (ET)
was admitted with severe abdominal pain that was due to sonographicall
y verified portal and hepatic vein thrombosis. ET is a well-documented
disease and portal vein thrombosis has often, been reported in adults
but not in children and adolescents suffering from ET. Coincidence of
ET, urinary tract infection, oral contraception, and cessation of ace
tylsalicylic acid therapy might be responsible for the early manifesta
tion of portal and hepatic vein. thrombosis in our patient.
