Solitary fibrous tumors (SFTs) rarely develop in the pelvis. When they do arise, they are usually treated using surgery, although SFTs are often very large by the time of diagnosis, which makes surgical excision difficult. We report a case of a 63-year-old man who was referred to our hospital for the treatment of a giant tumor of the pelvis. Computed tomography (CT) revealed a 30 × 25 × 19 cm sized hypervascular tumor that almost completely filled the pelvic cavity. The diagnosis of SFT was made by CT-assisted needle biopsy. The feeding arteries of the tumor were embolized twice. The first embolization aimed to reduce the tumor volume, while the second one was planned a day prior to the surgery to obtain hematostasis during the operation. Tumor resection was then performed. The blood loss during the operation was 440 ml, and there was no uncontrollable bleeding. The postoperative course was uneventful. No recurrence of SFT was observed during a 2-year follow-up.
孤立性纤维瘤（SFT）很少发生于骨盆。当它发生时，通常采用手术治疗，尽管SFT在诊断时往往已经非常大，这使得手术切除困难。我们报告一例63岁男性，因骨盆巨大肿瘤被转诊至我院治疗。计算机断层扫描（CT）显示一个大小为30×25×19 cm的高血管性肿瘤，几乎完全充满盆腔。通过CT引导下穿刺活检确诊为SFT。肿瘤的供血动脉进行了两次栓塞。第一次栓塞旨在缩小肿瘤体积，而第二次栓塞在手术前一天进行，以在手术期间实现止血。然后进行了肿瘤切除术。手术中失血440 ml，无不可控制的出血。术后病程平稳。在2年的随访中未观察到SFT复发。
