Solitary fibrous tumors (SFTs) and hemangiopericytomas (HPCs) have been combined into a single designation in the most recent World Health Organization (WHO) guidelines as solitary fibrous tumor/hemangiopericytoma (SFT/HPC). These rare intracranial tumors can present as WHO grade I, II, or III tumors, with the risk of recurrence, metastasis, and mortality worsening with higher-grade tumors. We present a case of a patient with a WHO grade III SFT/HPC with an emphasis on the imaging features that help differentiate this type of tumor from meningiomas, which are much more common and can appear similar. Being able to help differentiate these tumors by their imaging appearance is important to help triage and risk-stratify patient management decisions.
在世界卫生组织（WHO）最新指南中，孤立性纤维瘤（SFTs）和血管外皮细胞瘤（HPCs）已合并为一个名称，即孤立性纤维瘤/血管外皮细胞瘤（SFT/HPC）。这些罕见的颅内肿瘤可表现为WHO I级、II级或III级肿瘤，肿瘤分级越高，复发、转移及死亡风险越高。我们报告1例WHO III级SFT/HPC患者，重点介绍有助于将此类肿瘤与更为常见且可能表现相似的脑膜瘤相鉴别的影像学特征。通过影像学表现鉴别这些肿瘤，对于指导患者管理决策的分类和风险分层具有重要意义。
