Sinonasal hemangiopericytoma is a rare sinonasal mesenchymal tumor, and is considered different from other reported hemangiopericytomas. A 37-year-old man presented with intermittent left epistaxis for three days. Rhinoscopic examination revealed a smooth red mass in the left middle nasal meatus. A pathology report of the biopsy specimen showed sinonasal hemangiopericytoma. Magnetic resonance imaging demonstrated the tumor had eroded the posterior nasal septum, involved the bilateral posterior ethmoid sinuses, and obstructed the ostium of the left maxillary sinus causing left maxillary sinusitis. After transarterial embolization, the tumor was endoscopically excised with a microdebrider. The postoperative course was uneventful and epistaxis did not recur during the following two years. Follow-up magnetic resonance imaging did not show any tumor recurrence, although the bilateral maxillary sinusitis remained. Nevertheless, the patient should be followed regularly to exclude the possibility of recurrence or metastasis.
鼻及鼻竇血管外皮細胞瘤是一種罕見的鼻及鼻竇間質瘤，目前認為它與一般的軟組織血管外皮細胞瘤不同。一37歲男性，因間斷流鼻血3日求諮於本院。理學檢查發現左側中鼻道有一顆表面平滑的紅色腫塊，經切片後證實是鼻及鼻竇血管外皮細胞瘤。磁振造影顯示該腫瘤已傾犯後方鼻中隔及兩側後篩竇，並阻塞左側上領買賣口造成鼻竇炎。經動脈栓塞後，在內視鏡下以微形吸絞器切除之。爾後2年，情況穩定，不再流鼻血，磁振造影追蹤顯示兩側上頜竇炎依舊，但腫瘤並未復發，然而，本個案仍須長期追蹤以排除復發或轉移的可能性。
