title: Portal vein thrombosis in a 17-year-old female adolescent with essential thrombocytosis.
abstract: A 17-year-old girl known to suffer from essential thrombocytosis (ET) was admitted with severe abdominal pain that was due to sonographically 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 acetylsalicylic acid therapy might be responsible for the early manifestation of portal and hepatic vein thrombosis in our patient.
