摘　　要：目的分析眼眶炎性假瘤多层螺旋CT、磁共振影像学表现及诊断价值。方法回顾分析,收集在本院2017年9月至2019年6月收治的76例眼眶炎性假瘤患者的临床资料,所有患者均进行MSCT以及MRI检查。分析患者MSCT及MRI图像表现,并对比对两种检查方法对眼眶炎性假瘤的诊断正确率。结果MSCT检查确诊为眼眶炎性假瘤患者为74例,诊断正确率为97.36%,与MRI检查相比无差异(确诊75例,诊断率为98.68%,P>0.05);MSCT图像表现为灶性或弥漫性肿块,与周围组织交界不清楚,或呈现铸型关系,在增强后可见强化。并可见有眼外肌肥大、眼环增厚、视神经增粗等情况;MRI图像可见T1WI为等或稍长信号,T2WI为等、稍短或稍长信号。增强扫描病灶为明显中度强化,结论MSCT检查、MRI检查对眼眶炎性假瘤均有较高的诊断价值,可为临床诊断、治疗提供可靠参考依据。Objective To analyze the imaging features of the orbital inflammatory pseudotumor in the multislice spiral CT and magnetic resonance imaging and its diagnostic value.Methods The clinical data of 76 patients with orbital inflammatory pseudotumor admitted to our hospital from September 2017 to June 2019 were retrospectively analyzed.All patients underwent MSCT and MRI.The patient’s MSCT and MRI images were analyzed,and the diagnostic accuracy of the two methods for orbital inflammatory pseudotumor was compared.Results There were 74 patients diagnosed with orbital inflammatory pseudotumor by MSCT.The diagnostic accuracy was 97.36%.There was no difference compared with MRI(75 cases were diagnosed,and the diagnostic accuracy was 98.68%)(P>0.05).The MSCT image showed a focal or diffuse mass,and the boundary with the surrounding tissue was unclear,or it showed cast relationship,and enhancement was observed after enhancement.There was also extraocular muscle enlargement,thickening of the ring plate,thickening of the optic nerve,etc.The MRI image showed that the T1WI was an equal or slightly longer signal,and the T2WI was an equal,slightly shorter,or slightly longer signal.The enhanced scan showed that the lesion was significantly moderately enhanced.Conclusion MSCT examination and MRI examination have higher diagnostic values for orbital inflammatory pseudotumor,providing a reliable reference for clinical diagnosis and treatment.
