痛性眼肌麻痹综合征的MRI诊断

目的 探讨痛性眼肌麻痹综合征在磁共振成像（magnetic resonance inaging,MRI）中的表现,为痛性眼肌麻痹综合征的临床诊断提供客观的影像学依据。方法 对临床确诊的17例痛性眼肌麻痹综合征患者,分别行眶区和（或）海绵窦区MRI平扫和脂肪抑制钆-二乙烯三胺五乙酸（gadolinium-diethylene triamine pentaacetic acid,Gd-DTPA)增强扫描。结果 痛性眼肌麻痹综合征MRI表现为眶上裂区斑片状或小结节状异常信号,患者海绵窦增大、增宽,眶上裂和海绵窦邻近的颞叶脑膜局限性受累。结论 MRI脂肪抑制Gd-DTPA增强扫描可清晰显示痛性眼肌麻痹综合征的病变;MRI检查可为临床诊断痛性眼肌痹综合征提供客观、可靠的影像学依据。

MRI diagnosis of painful ophthalmoplegia syndrome

Objective To study MRI appearances of painful ophthalmoplegia syndrome and provide image basis for clinical diagnosis of painful ophthalmoplegia syndrome. Methods Seventeen cases with painful ophthalmoplegia syndrome diagnosed clinically were collected. MRI ordinary scan and gadolinium diethylene triamine pentaacetic acid (Gd DTPA) contrast fatty restraint scan were performed on the orbit and cavernous sinus. Results MRI appearances of painful ophthalmoplegia syndrome included patch or small nodule abnormal signal at the region of fissura orbitalis superior. The ipsilateral cavernous sinus was enlarged. The local lobus temporalis meninges close to the fissura orbitalis superior and cavernous sinus were invaded. MRI contrast fatty restraint scan might clearly show the pathological changes. Conclusion MRI may provide image basis for the clinical diagnosis of painful ophthalmoplegia syndrome.
