目的 回顾性分析１４ 例原发性眼球肿瘤的ＣＴ 影像学表现。方法 对１４ 例临床诊断为原发性眼球肿瘤的住院病人，采用ＳＨＩＭＡＤＺＵＳＣＴ５０００Ｔ 全身ＣＴ进行扫描，部分病人同时行增强扫描，所有病例均经手术和病理证实。结果 视网膜母细胞瘤８ 例，均为儿童发病，ＣＴ 表现为玻璃体腔内软组织肿块，靠近眼球后部，大部分可显示明确的钙化，并可经视神经引起眶内外转移；脉络膜黑色素瘤６ 例，成人发病，ＣＴ 表现为突向腔内的高密度肿块或眼环的局限性增厚，中度强化，钙化少见，部分病例可继发视网膜剥离。结论 原发性眼球肿瘤根据发病年龄和ＣＴ 影像特征不难作出定性诊断。
Objective To retrospectively analyze the CT findings of 14 cases of primary ocular tumors. Methods Fourteen clinically diagnosed primary eye tumor patients were scanned with SHIMADZUS CT5000T whole body CT, and some patients underwent simultaneous enhanced scan. All cases were confirmed by surgery and pathology. Results 8 cases of retinoblastoma, all children with CT manifestations of intravitreal soft tissue mass, close to the posterior eye, most of the calcification can be shown, and can cause intraorbital transfer of the optic nerve; 6 cases of choroidal melanoma, Adult onset, CT showed a high density of intracavitary lesions or eye ring limitations of thickening, moderate enhancement, calcification rare, in some cases may be secondary to retinal detachment. Conclusion The primary tumor of the eye is not difficult to make a qualitative diagnosis according to the age of onset and CT image features.
