【摘要】 目的:评价CT检查对眼葡萄膜黑色素瘤的CT诊断价值。材料与方法:本组原发性黑色素瘤27例病人33个眼球受累(其中21例经手术切除后获得病理证实,另外6例因双眼同时受累由随访证实),所有病例均经CT平扫及强化扫描。结果:CT扫描表现为:①形状:半圆形、蘑菇云状或弥漫性突入眼球;②大小:1～5mm(n=5)、6～10mm(n=6)、11～15mm(n=18)、15mm以上(n=4);③密度:均匀(n=23)、伴有钙化(n=6)、伴有囊性变(n=4);④病变侵及或侵出眼球(n=14);⑤合并视网膜脱离(n=5)。结论:CT检查对原发性眼葡萄膜黑色素瘤诊断有特异性,能清晰显示病变的大小、范围及与眼球周围组织的关系,但仍需要与一些其他常见病进行鉴别并随访观察。更多还原

【Abstract】 Objective: To evaluate the value of CT in diagnosing uveal melanoma. Methods: 27 patients with primary intraocular tumors in 33 globes were studied by CT(6 cases with double eyes were verified with follow-up studies,the other 21 single eyes with surgical histopathological diagnosis). Results: CT findings include:1. Shape:sharply marginated lesions appearing as a round ,oval or me-nis-cus-shaped thicking of the wall of the eye: 2. Size: 1 -5mm ( n = 5 ) ,6-10mm ( n = 6 ) ,11 -15mm ( n = 8 ) , over 15mm ( n = 4 ) ; 3. Density: elevated dense with moderate enhancement (6 cases with calcification, 5 cases with cystic degeneration) ; 4. Invasion through or over the wall of the eye (n = 14) ; 5. Combining with retinal detachment (n =5). Conclusion; It is specific to diagnose primary uveal melanoma by CT in showing the lesions size, range and invasion, but it is necessary to differentiate with some common diseases.更多还原
