摘　　要：目的探讨眼眶肌锥内病变磁共振成像(MRI)影像表现及鉴别诊断的应用价值。方法回顾和分析34例经手术病理及临床治疗随访证实眼眶肌锥内病变MRI表现。结果共发现眼眶肌锥内病变病灶35个,左眼16例、右眼17例,双眼1例。脉管源性肿瘤23例,其中海绵状血管瘤18例,表现为T_1WI稍低T_2WI高信号卵圆形肿块;脉管瘤2例,表现为T_1WI稍低T_2WI高信号卵圆形肿块;静脉性血管瘤3例,表现结节状或斑片状肿块,T_1WI为低信号,T_2WI为血管流空混杂信号;神经源性肿瘤5例,表现为T_1WI稍低T_2WI高或混杂高信号肿块;炎性病变4例表现T_1WI等T_2WI等、稍高或稍低信号肿块;淋巴瘤2例,表现片块状T_1WI等信号肿块,T_2WI稍高信号肿块;间叶软骨肉瘤1例表现为结节状T_1WI稍低T_2WI混杂稍低信号肿块。结论 MRI能清晰显示眼眶肌锥内病变的影像学特征,对于眼眶肌锥内病变的诊断、鉴别诊断和术前定位具有重要价值。Objective To investigate the lesions of the orbital cone compartment′s MR imaging representation and the value clinical application. Methods To review and analyze MR imaging representation of 35 patients within orbital muscle cone compartment disease,confirmed by surgical pathology or follow-up were retrospectively analyze. Results Totally find out 35 lesions in orbital cone compartment, including 16 cases in left eye, 17 cases in right eye,and 1 case in both eyes. Vascular tumoraccount for 23 cases, In those cases, cavernous hemangioma take up 18 cases, which showed oval mass and lower single in T1WI and high single in T2WI,vascular tumor take up 2 cases, which showed oval mass and lower single in T1WI and high single in T2WI,venous hemangioma take up 3 cases, which showed amorphous plaques mass and slightly lower or high signal in T 1WI and high or mixed signal and no signal blood vessels in T2WI ;neurogenic tumour take up 5 cases,which showed low single in T1WI and high or mixed signal in T2WI;inflammatory disease in 3 cases showed amorphous plaquesor nodular and isointensity signal in T1WI and T2WI ;lymphoma account for 2 cases, which showed amorphous plaques mass ,showed isointensity in T1WIand higher signal in T2WI; 1 cases in mesenchymal sarcoenchondroma showed nodular,slight low single in T1WI and lower mixed signal in T2WI. Conclusion MR imaging can clearly show lesion in orbital compartment, on the other hand, MR imaging is worth of differentiation, diagnosis and preoperative localization for occupied lesionsin orbital muscle cone′s compartment.
