Solitary fibrous tumors (SFT) are rare, ubiquitous neoplasms of mesenchymal origin, with distinctive histopathological and immunohistochemical features. We herein report an unusual case of a presacral SFT diagnosed in an asymptomatic 40-year-old woman preoperatively investigated with computed tomography and magnetic resonance imaging. Post-operative pathology examination showed a SFT containing foci of extramedullary hematopoiesis. Revision of preoperative imaging did not evidenced any findings suggesting this unusual association. The patient was free from local recurrence and metastases one year after operation. Differential radiological and histological diagnoses of solid presacral masses is briefly discussed.
孤立性纤维性肿瘤（SFT）是一种罕见的、起源于间充质的全身性肿瘤，具有独特的组织病理学和免疫组化特征。我们在此报告一例罕见的骶前SFT病例，该病例发生在一名40岁无症状女性身上，术前通过计算机断层扫描和磁共振成像进行了检查。术后病理检查显示SFT含有髓外造血灶。术前影像复查未发现任何提示这种异常关联的表现。患者术后一年无局部复发和转移。本文简要讨论了骶前实性肿块的鉴别影像学和组织学诊断。
