摘　　要：目的探讨颅内血管外皮瘤（hemangiopericytomas，HPC）的MRI影像表现并与病理学进行对照，皆在总结HPC的MR／特点，提高其诊断符合率。方法搜集经手术病理证实的颅内HPC10例，分析其影像学表现，并与病理及免疫组织化学结果行对照分析。结果10例HPC8例单发，2例多发，8例分叶状，7例窄基底与硬膜附着，T1WI肿瘤呈等信号，T2WI肿瘤呈等、高信号，DWI呈等高信号，7例瘤体内可见迂曲血管，7例可见坏死、囊变，5例可见瘤周水肿。10例免疫组化均显示瘤细胞Vimentin，CD34阳性，Ki-67阳性（5％-15％）。结论HPC具有分叶状，T2WI、DWI呈稍高信号，肿瘤内部有迂曲血管等MRI特点，借助病理学及免疫组织化学可以明确诊断。Objective To explore the magnetic resonance imaging （MR/） findings and pathologic features of intracranial hemangioperieytoma （HPC） and to improve the diagnostic coincidence rate. Methods A total of 10 patients with HPC confirmed by pathological and results were analyzed with imaging appearance, pathological and immunohistochemical characteristics. Results 8 of 10 cases are single, 2 cases are multiple.8 cases are multilobulated and 7 cases are narrow-based. On TlWI, all cases show intermediate signal. On T2WI, all cases show iso＇ and hyperintensity. On DWI, all cases show high signal. 7 cases can see serpentine signal voids. 7 cases can see cystic degeneration or necrosis in tumor. 5 cases can see peritumoral edema. On immunohistochemistry, the tumor cells show Vimentin （＋）, CD34 （＋） and Ki-67 （＋） （5% ～ 15%）. Conclusion HPC with lobulated, T2WI, DWI has a slightly higher signal, and shows blood vessels such as MRI as distinguished feature of tumor with the aid of pathology and immunohistochemical for clear diagnosis.
