title: Selective intra-arterial Y-90 microsphere therapy in hemangioendothelioma.
abstract: Epithelioid hemangioendothelioma is a malignant soft tissue tumor originating from the endothelial cell. Its clinical course varies from benign hemangioma to angiosarcoma. The therapy procedure remains unclear. Although resection of the tumor is the most frequently suggested treatment, due to its multinodular type, transplantation is frequently performed. Therapy regimens other than transplantation and resection are not effective and the median survival in hemangioendothelioma with unresectable lesions is approximately eight months. In this case, we report the therapeutic effect of selective intra-arterial radionuclide yttrium (Y)-90 microspheres and the value of F-18 fluorodeoxyglucose positron emission tomography/computed tomography to evaluate therapy response in hemangioendothelioma.
