title: Portal Hypertension Caused by Immature Teratoma in an Adolescent Female.
abstract: BACKGROUND
  Tumor compression is a cause of portal hypertension. In adolescents, most tumors are germ cell tumors.
  
  
  METHODS
  We report the case of a 17-year-old female patient with progressive abdominal distention. Portal hypertension with ascites and esophageal varices were identified. A computed tomography scan showed a large ovarian mass that was consistent with a teratoma. After laparotomy, the portal hypertension was resolved.
  
  
  CONCLUSIONS
  Venous compression by an immature teratoma should be considered a cause of portal hypertension in adolescents.
