Acute hemorrhage from a retroperitoneal liposarcoma treated by embolization

Liposarcomas are rare retroperitoneal mesenchymal tumors that present at an advanced stage and often have poor prognoses. These malignant tumors create a diagnostic conundrum and pose several treatment difficulties due to their rarity and anatomic placement. Retroperitoneal liposarcomas often present as asymptomatic abdominal tumors and rarely cause acute bleeding. Surgery is typically required in cases with acute malignant bleeding and hemodynamic instability. Angioembolization and other bleed-control methods should be researched where available. This case report describes the case of a 17-year-old male patient whose tumor had an acute abdominal hemorrhage treated by embolization.
