血管外皮瘤是一種相當少見的軟組織腫瘤，好發部位以下肢，後腹腔或骨盆腔佔多數，而咽喉、脾臟、骨骼、腦膜、胸腔則是較少出現的部位。我們報告一個35歲顱內血管外皮瘤的男性病例，在顱骨切開術與部份腫瘤切除後接受手術後的放射線治療。使用傳統放射線治療技術給予殘餘腫瘤部位63 Gy/35次的放射劑量。經過10年的追蹤，磁振造影檢查並無腫瘤復發。這個病例在接受手術與放射線治療後獲得長期的腫瘤控制。

Hemangiopericytomas are rare soft tissue tumors that develop mainly in the lower extremities, retroperitoneum or pelvis and rarely occur in the larynx, spleen, bone, meninges or thorax. This case is that of a 35-year-old man with intracranial hemangiopericytoma which was treated with craniotomy and partial removal of tumor. This was followed by post operative radiotherapy using conventional wedge pair technique with total dose of 63 Gy in 35 fractions to the residual tumor. MRI (magnetic resonance image) of brain showed no recurrence or other abnormal finding at a 10-year follow-up. The patient has long-term tumor control after surgery and post-operative radiotherapy.
