摘要
目的:观察和探讨中枢神经系统血管外皮细胞瘤的MRI及CT影像学特点,以提高诊断水平。方法:回顾性分析2010年2月到2017年10月经手术病理证实的中枢神经系统血管外皮细胞瘤6例。6例行MRI平扫及增强,6例行CT平扫,5例增强。结果:5例位于颅内脑外,1例位于髓外硬膜内;CT上,6例均为高密度肿块,2例伴坏死,1例伴钙化,增强后5例均明显强化,3例伴脑膜增厚强化。MRI上,4例(66.67%)呈与脑白质等信号的稍短T1信号,1例呈与灰质等信号的等T1信号,1例呈稍长T1信号;T2WI上,5例(83.3%)呈与灰质等信号的T2信号,1例呈稍长T2信号;增强后5例均明显强化,囊变坏死无强化,4例(66.67%)邻近硬脑膜或脊膜均增厚、强化,3例(50.0%)见典型"脑膜尾征";4例(66.67)颅内病灶伴水肿。2例伴骨质破坏。结论:中枢神经系统血管外皮细胞瘤具有一定的CT、MRI特征性,最终诊断依靠病理。
Objective： To observe and discuss the central nervous system of hemangiopericytoma MRI and CT imaging features,in order to improve the diagnostic level. Methods： From February 2010 to October 2017 were retrospectively analyzed surgical pathology confirmed 6 cases of hemangiopericytoma of central nervous system. 6 routine MRI scan and enhancement,6 underwent CT scan,5 cases were enhanced. Results： 5 cases located in intracranial brain,1 case of triangle is located in the lateral ventricle,2 cases of intramural outside of pulp; On CT,6 cases were high density lump,2 cases with necrosis,1 cases with calcification,5 cases were significantly enhancement,3 cases with dura thickening reinforcement. On MRI,4 cases（66. 67%） and cerebral white matter signal slightly shorter T1 signal,1 case of signals,such as gray matter such as T1 signal,1 case with slightly long T1 signal; On T2 WI,5 cases（83. 3%） and gray matter such as signal of T2 signal,1 case was slightly long T2 signal; 5 cases were significantly enhancement,cystic necrosis without reinforcement,4 cases（66. 67%） of the adjacent dura thickening or meninges,improved,3 cases 50. 0%）,as shown in the typical meningeal tail;4 cases（66. 67%）,intracranial lesions associated with edema. 2 cases with bony destruction. Conclusion： The central nervous system hemangiopericytoma have certain characteristic CT,MRI,the final diagnosis depends on pathology.
