多発性頭蓋外転移を来たしたHemangiopericytomaの1例

A Case of Hemangiopericytoma with Multiple Extracranial Metastasis : a case report

I．はじめに

　Hemangiopericytomaは血管に富み，急速に増大する腫瘍で，頭蓋外に転移することがしばしばみられる．今回われわれは脳腫瘍で発症し，肝臓，肺，脊椎，膵臓に転移を繰り返しながらも，手術を主体とする治療で，20年間大きな機能障害無く生存中の症例を経験したので報告する．

A case of a patient with hemangiopericytoma with multiple extracranial metastasis, who has survivedfor more than twenty years is reported. A fifty-five-year-old male presented brain tumor twenty years ago.He underwent total removal of the tumors, but recurrences occurred each time, Liver metastasis was foundseven years ago. After that multiple metastases extended to the lung, vertebra and pancreas and operationsand irradiations were performed. At present, there is no progression of the tumors and he enjoyed a highquality of life. We concluded that, to ensure long time survival, a patient with hemangiopericytoma mustbe monitored carefully for local recurrence and systemic metastases.
