摘要
目的 :探讨常见眼球内肿瘤的CT表现及其在诊断与鉴别诊断中的价值。方法 :分析经手术病理证实的 47例眼球内肿瘤的CT表现 ,其中平扫 47例、平扫加增强扫描 37例。结果 :视网膜母细胞瘤 2 9例 ,CT表现自眼环生长的软组织肿块并钙化为本病特征表现 ,葡萄膜黑色素瘤 13例 ,脉络膜血管瘤 1例 ,脉络膜转移瘤 2例 ,CT均表现起自眼环的软组织肿块 ,无钙化 ;脉络膜骨瘤 2例 ,CT表现眼环类圆形骨密度肿瘤。结论 :CT可确定眼球内肿瘤的位置并提示肿瘤的性质 ,对视网膜母细胞瘤进行确切的诊断及分期 。
Objective:To study the CT finding and the evaluation of diagnosis in common eyeball tumors.Methods:Forty-seven cases with eyeball tumor were proved by surgery and pathology.pre-contrast scanning is preformed in all cases,both pre-contrast and post-contrast scanning in thirty-seven cases.Results:The CT specific signs of 29 cases with retinoblastoma were scleral mass with calcification;Uveal melanoma,choridal hemangioma and choroidal metastasis were 13 cases,1 cases and 2 cases respectively.The CT signs is the scleral mass without calcification;choroidal osteoma was 2 cases.the CT signs were mass with osseous density.Conclusion:CT can locate and show the nature of the eyeball tumors and can exactly diagnosis and classifiy retinoblastoma,so that CT can give significant evidence for clinic.
