【摘要】 目的:作者报告眼眶血管瘤的影像诊断与分型,以帮助临床及时诊断和治疗,提供可靠依据。材料和方法:对经X线、B超、CT检查、手术病理证实的眼眶血管瘤41例影像表现,作了回顾性的分析,并进行了分型。结果:41例眼眶血管瘤的影像表现:1、眼眶扩大5例,眼眶周围及眶内软组织肿块密影,大小不等;2、眼静脉造影可见内眦静脉或上眼静脉增粗,血管瘤引流血管显示;3、眼底荧光血管造影见视网膜血管迂曲、扩张,血管团影;4、B超表现为回声稍强光团或低回声光团;5、CT表现为眼球凸出,球后肿块密影呈园形、椭园型,增强扫描有较明显强化。作者根据本组41例血管瘤的影像学表现与手术所见,把眼眶血管瘤按发生部位和范围分为二型:即局限型和弥漫型。局限型血管瘤又分为,(1)限脸皮下血管瘤;(2)球后眶内血管瘤;(3)球结膜血管瘤;(4)视网膜血管瘤;(5)脉络膜血管瘤。结论:分型有利于临床治疗。更多还原

【Abstract】 Purpose: The authors reported imaging characteristics and classification of orbital angioma in order to help clinical diagnosis and treatment. Material and method: Retrospective analysis of imaging manifestations and classification wre performed in 41 cases of orbital angioma whom were confirmed by conventional X - ray, B - mode ultrasound and CT examination as well as surgery and pathology. Results: Imaging characteristics; 1. orbital enlargement pe-riophthalmic and periorbital soft tissue mass with varied size were found in five cases; 2. Engorged angularis vein and superior ophthalmic vein as well as drain veins of angioma were seen in ophthalmic veinography;3. Fundus oculi fluo-rescein angiograms showed tortuous and engorged retinal vesseles and vascular mass;4. B - mode ultrasound showed mild strong echo mass or hypoechoic mass;5. CT manifestations were proptosis retrobulb mass with round or oval shape relative obvious enhancement of lesions were noticed in CT contrast enhancing scan. Based on imaging manifestations and surgical findings in 41 cases of orbital angiomas, the authors dividied orbital angioms into two types according to their location and extension:local type and diffuse type.The local type can be further divided into the following: (1) palpebral subcutaneous angioma; (2)intraorbital retrobulbar angioma; (3)angioma of conjunctive bulbar; (4)retinal angioma; (5)choroidal angioma. Conclusion:classification of orbital angioma is helpful to clinical treatment.更多还原
