眼眶占位性病变的CT诊断与手术方式的相关性分析

The significance of CT diagnosis for the selection of type of operation in orbital space occupying lesions

目的 :探讨眼眶占位性病变的CT影像特点 ,从而指导治疗及手术方式的选择。方法 :分析我院主要经手术、病理证实的 5 9例眼眶占位性病变的CT征象、临床资料及手术方式。结果 :眼眶原发良性肿瘤 3 5例 ,原发恶性肿瘤 6例 ,炎性假瘤 11例 ,颈动脉海绵窦瘘 7例。 7例颈动脉海绵窦瘘经CT及DSA诊断明确并行栓塞治疗 ,41例眼眶肿瘤及 8例炎性假瘤在CT定性、定位结论的指导下行手术治疗均完整切除肿块 ,另 2例肌炎型及 1例肿块型炎性假瘤经皮质激素治疗后明显缓解。结论 :CT可对眶内病变进行准确定位并估计病变的性质 ,为治疗及手术进路的选择提供了有价值的参考。

Objective:To investigate the CT features of intraorbital space occupying lesions,so as to conduct the treatment and approaches to orbitotomy.Methods:We analysed the CT features,clinical presentations,methods of treatment and approaches to orbitotomy in 59 cases of orbital space occupying lesions,most of which had been confirmed by operation and pathology.Results:Thirty five cases of benign tumor,6 cases of primary malignant tumor,11 cases of idiopathic pseudotumor and 7 cases of carotid cavernous fistula were found in this group.All cases of CCF were diagnosed accurately by CT scanning and treated with embolization.Forty one orbital tumors and 8 IOPT were completely resected in virtue of CT scanning.Conclusion:CT can locate the lesions and characterize the nature of the lesions,and play important role in the selection of the treatment and approaches to orbitotomy.
