摘　　要：目的研究在对中枢神经系统血管外皮细胞瘤与脑膜瘤鉴别诊断中CT、MRI应用价值。方法回顾性分析我院2019年1月1日至2021年12月31日期间41例中枢神经系统血管外皮细胞瘤与74例脑膜瘤患者临床资料,收集其CT、MRI影像学资料,比较两组患者形态学特征及相对灌注参数。结果脑膜瘤患者分叶征、不均匀强化检出率较中枢神经系统血管外皮细胞瘤低,宽基底、骨质增生检出率较中枢神经系统血管外皮细胞瘤高(P<0.05);脑膜瘤患者CT检查中局部脑血流量(RCBF)、局部脑血容量(RCBV)水平较中枢神经系统血管外皮细胞瘤低,MRI检查中局部脑血流量(Rr CBF)水平较中枢神经系统血管外皮细胞瘤低(P<0.05)。结论中枢神经系统血管外皮细胞瘤与脑膜瘤在影像学征象、血流灌注情况中较相似,但两者在分叶征、不均匀强化、骨质增生、局部血流灌注情况比较中仍存在差异,可用于鉴别诊断。Objective To investigate the application value of CT and MRI in the differential diagnosis of hemangiocytoma and meningioma of the central nervous system.Methods Clinical data of 41 cases of hemangiocytoma of central nervous system and 74 cases of meningioma in our hospital from January 1,2019 to December 31,2021 were retrospectively analyzed.CT and MRI imaging data were collected,and morphological characteristics and relative perfusion parameters of the two groups of patients were compared.Results The detection rate of lobular sign and uneven enhancement in meningioma patients was lower than that of hemangiocytoma of central nervous system,but the detection rate of widebase and hyperplasia of bone was higher than that of hemangiocytoma of central nervous system(P<0.05).The levels of local cerebral blood flow(RCBF)and local cerebral blood volume(RCBV)in meningioma patients were lower in CT examination than in hemangiocytoma of central nervous system,and the levels of local cerebral blood flow(RrCBF)in MRI examination were lower than that in hemangiocytoma of central nervous system(P<0.05).Conclusion Angiocytoma and meningioma of the central nervous system are similar in imaging signs and blood perfusion,but there are still differences between the two in the comparison of lobular signs,uneven enhancement,bone hyperplasia and local blood perfusion,which can be used for differential diagnosis.
