摘要
目的探讨颅骨脑膜瘤的CT及MRI表现特征。方法回顾性分析自2008年1月至2020年12月于乐清市人民医院和温州市人民医院神经外科术后病理证实为颅骨脑膜瘤的20例患者的CT及MRI表现。结果20例患者中,颅骨溶骨性破坏14例,成骨性破坏4例,混合性破坏2例;伴软组织肿块12例,伴辐射状骨针11例。16例患者CT检查示密度均匀10例,不均匀6例;高密度影8例,等密度影5例,低密度影3例;伴钙化5例。17例患者MRI检查示信号均匀11例,信号不均匀6例;T1WI稍低信号12例,等信号5例;T2WI稍高信号12例,稍低信号5例;弥散加权成像(DWI)高信号12例,稍高信号5例。增强扫描后示均匀强化12例,不均匀强化8例;有"脑膜尾征"13例,有瘤周水肿11例。结论颅骨脑膜瘤患者的骨质以溶骨性或成骨性破坏伴软组织肿块、辐射状骨针为主,CT示肿瘤密度均匀或不均匀,MRI示信号均匀或不均匀,增强扫描时多有"脑膜尾征"。
Objective To investigate the CT and MRI features of meningiomas of the skull.Methods A retrospective analysis was performed;the CT and MRI findings of 20 patients with meningiomas of the skull confirmed by pathology after surgery in our hospital from January 2008 to December 2020 were collected.Results Fourteen patients had skull osteolytic destruction,4 had osteogenic destruction,and 2 had mixed destruction.There were 12 patients with soft tissue masses and 11 with radial spicules.In 16 patients accepted CT examination,uniform density was noted in 10 and uneven density in 6;8 had high density,5 had equal density,and 3 had low density;5 patients were with calcification.In 17 patients accepted MRI examination,11 had uniform signal and 6 had un-uniform signal;T1WI had slightly low signal in 12 patients and equal signal in 5 patients;T2WI had slightly high signal in 12 patients and slightly low signal in 5 patients;diffusion weighted imaging(DWI)had high signal in 12 patients and slightly high signal in 5 patients.Totally,enhanced homogeneous enhancement was noted in 12 patients and inhomogeneous enhancement was noted in 8 patients;and there were 13 patients with"meningeal tail sign"and 11 with peritumoral edema.Conclusion Bone in patients with meningiomas of the skull is characterized by osteolytic or osteogenic destruction with soft tissue masses and radial spicules;CT shows uniform or un-uniform tumor density,MRI shows uniform or un-uniform signals,and enhanced"meningeal tail sign"is characterized.
