眼球内常见病变CT诊断 　　[摘要] 目的 本文回顾性分析25例眼球内病变的CT表现,以期进一步提高对眼球病变的认识。方法 25例病人均行CT平扫和增强,使用日本东芝公司生产的单螺旋CT。结果 视网膜母细胞瘤9例,表现为眼球内高密度肿块、钙斑及球外侵犯;脉络膜黑色素瘤6例,表现为眼球后部肿块,多明显强化;Coat’s病2例,表现为眼球玻璃体内密度弥漫性增高,CT值60～88HU;转移瘤4例,表现为眼球后壁扁平局限性增厚,向球内隆起;视网膜剥离4例,表现为眼底弧形隆起,尖端呈“V”形,汇集于视神经入眼底处。结论 CT是发现和诊断眼球内病变的重要检查手段,对绝大多数疾病可做出正确诊断。 　　[关键词] 眼球内肿瘤; 视网膜母细胞瘤; 视网膜剥离; CT 　　[中图分类号] R814.42 [文献标识码] A [文章编号] 1673-9701(2010)05-77-02 　　 　　CT Diagnosis of Intraocular Lesions 　　HU Qiuliang TANG Zhihui 　　Department of Radiology,the First TCM Hospital of Yiyang City,Yiyang 413000,China 　　 　　[Abstract] ObjectiveTo make a retrospective analysis of CT findings of 25 cases of eye lesions in an attempt to enhance the understanding of eye lesions. MethodsPlain CT scan and contrast CT scan were carried out in 25 patients with a single-spiral CT made by Japanese Toshiba Corporation. ResultsNine cases were retinoblastoma,with high-density mass within the eye,calcium spots,and the violations outside the ball,6 cases of choroidal melanoma showed the mass in the back part of the eye,more obviously enhanced,2 cases of coats disease showed diffuse increased density within the eye glass with CT value from 60 to 88 HU,4 cases of matastosis showed the thickened flat limitation in the posterior wall of the eyeball,making a bulge towards the eyeball and 4 cases of retinal detachment showed the fundus arc uplifts with “V”- shaped cutting-edge,pooling at the entrance of the optic nerve into the fundus. ConclusionCT is in an important examination means for the detection and diagnosis of eye lesions,and a correct diagnosis of the vast majority of eye diseases can be made by using CT. 　　[Key words]Eye neoplasms; Retinoblastoma; Retinal detachment; Computerized tomography 　　 　　总结我院2001～2007年确诊的25例眼球内病变的CT表现,结合有关文献,回顾眼球病变的CT诊断与鉴别诊断,以期进一步提高对眼球病变的认识。 　　1 资料与方法 　　1.1 一般资料 　　25例眼球内病变包括视网膜母细胞瘤9例、脉络膜黑色素瘤6例、Coat’s病2例、转移瘤4例、视网膜剥离4例。9例视网膜母细胞瘤中,男5例,女4例;发病年龄1.5～9岁,平均3.6岁。6例脉络膜黑色素瘤中,男5例,女1例;年龄28～58岁,平均43岁。两例Coat’s病中,男1例,年龄8岁;女1例,年龄12岁。转移瘤中,
