摘　　要：目的探讨脊柱椎管内孤立性纤维瘤(SFT)/血管外皮细胞瘤(HPC)影像学特征及病理资料特点,以提高此类疾病的诊断水平。方法回顾性分析2012年4月—2021年1月我院7例经病理证实的椎管内SFT/HPC的CT、MRI及病理资料。结果本研究中包含WHOⅡ级3例(42.8%),WHOⅠ级3例(42.8%),WHOⅢ级病例1例(14.3%)。WHOⅠ级的Ki-67表达水平低于WHOⅡ、Ⅲ级。其中6例为单发病灶,1例为多发病灶;CT平扫均呈等密度;MRI平扫T1WI呈等信号,T2WI多表现为均匀稍低信号,增强后多明显均匀强化,可合并出血、囊变;WHOⅢ级病灶出现邻近骨质破坏。结论发生于脊柱椎管内的SFT/HPC具有特征性的影像学表现,与椎管内其他常见的肿瘤性病变有一定鉴别意义。Objective To investigate the imaging features and pathological data of solitary fibrous tumor(SFT)/hemangiopericytoma(HPC)in spinal canal,so as to improve the diagnosis of such diseases.Methods The CT,MRI and pathological data of 7 cases of intraspinal SFT/HPC confirmed by pathology were retrospectively analyzed.Results This study included 3 WHO Grade Ⅱ cases(42.8%),3 WHO Grade I cases(42.8%),and 1 WHO grade Ⅲ case(14.3%).The expression level of Ki-67 in WHO grade I was lower than that in WHO gradeⅡandⅢ.There were 6 cases of single lesion and 1 case of multiple lesion.CT plain scan showed equal density.MRI plain scan T1WI showed equal signal.T2WI usually shows uniform and slightly lower signal,and uniform enhancement after enhancement is obvious,which may be complicated with hemorrhage and cystic change.WHO Grade Ⅲ lesions showed adjacent bone destruction.Conclusion The SFT/HPC in the spinal canal has characteristic imaging findings and has certain differential significance from other common tumor lesions in the spinal canal.
