[A case of primary splenic angiosarcoma with intraperitoneal hemorrhage treated by transcatheter arterial...

Splenic tumors are very rare. In Japan only 42 cases of splenic angiosarcoma have been reported. We encountered a case of spontaneous rupture of a splenic angiosarcoma and liver metastasis. A 60-year-old woman who suddenly went into hemorrhagic shock presented at our hospital. Then acute spontaneously ruptured spleen and hepatic tumors were diagnosed by abdominal CT. After emergency TAE, the patient was hemodynamically stable, but died of liver failure 13 days after admission. The pathological diagnosis was primary splenic angiosarcoma with multiple organ metastasis on autopsy. Splenic angiosarcoma should be kept in mind in the differential diagnosis of splenomegaly or splenic tumor. TAE can be effective in primary hemostasis for angiosarcoma with intraperitoneal hemorrhage from multiple tumors.
