痛性眼肌麻痹影像学表现8例报告

目的:探讨Tolosa-Hunt综合征(THS)的影像学表现,为其临床诊断提供客观依据.方法:对1998～2006年临床确诊的8例THS进行回顾性研究,分析其CT、MRI平扫及增强扫描、DSA、磁共振血管成像(MRA)的表现.结果:影像学表现异常5例,主要表现为一侧海绵窦增大、眶尖软组织肿块.CT呈软组织密度,T1WI呈等信号或稍低信号,T2WI呈稍高、稍低信号或等信号;强化扫描CT、MRI均示病变明显强化,同时伴有邻近硬膜强化.DSA检查1例示病侧颈内动脉海绵窦段稍狭窄,MRA检查1例示一侧颈内动脉海绵窦段狭窄,形态不规则;另3例无明显异常表现.结论:THS部分病例有影像学的异常改变, CT、MRI表现对其确诊有重要价值.

The imaging performance of Tolosa-Hunt syndrome (8 example)

Objective:Goal:Provide foundation for the clinical diagnosis Through by Discussing the Imaging performance of Tolosa Hunt syndrome (THS).Methods:Retrospective researching 8 example THS clinical diagnosis between 1998 and 2006,analyzing performance of CT,MRI planar-scanning and enhanced-scanning, DSA,Magnetic resonance Angiography MRA.Results:Five in eight examples' imaging expresses abnormal,mainly performance increases for one side sinus cavernosus,Orbital apex soft tissue mass.CT assumes the soft tissue density,MRT1WI assumes the equisignal either the slightly low signal,T2WI assumes is slightly high,the slightly low signal or the equisignal;The enhanced-scanning CT,MRI both show the pathological change obvious strengthening,simultaneously showing the hard membrane strengthening in close.DSA inspects in one illustration sickness side neck the artery sinus cavernosus section to be slightly narrow,MRA inspects in one illustration one-side neck the artery sinus cavernosus section to be narrow, the shape is anomalous.Another three examples exceptionally display not obviously.Conclusion:The THS partial cases have the phantom study unusual change,CT,the MRI performance have the important value to its diagnosis.
