摘　　要：本文报告在我中心诊治经临床和病理检查证实的视网膜母细胞瘤(Rb)患儿52例(61眼)的 CT 扫描结果;介绍和讨论了 Rb 的 CT 图象特征和应用价值.本组 CT 扫描对 Rb 的检出率高(96.72%).Rb 瘤体钙斑发现率高(90.16%);Rb 瘤体显示软组织影及强化扫描后的轻度增强;Rb 的眼眶受累及颅内侵犯(包括3例颅内蔓延和1例三侧性 Rb)均为特征性表现.作者认为临床表现和其它检查可疑的 Rb 病例或怀疑 Rb 向眶内,颅内侵犯及双侧性 Rb 患儿作 CT 扫描有重要价值.文中讨论了诊断和鉴别诊断中需要注意的问题.眼科学报 1993;9:61-65。The results of CT scan in 52 patients(61 eyes)with retinoblastoma(Rb)managed and confirmed by clinical and pathalogical examination ate reported.The features and value of imaging of CT scan are described and discussed.In this series,96.72% of cases revealed Rb and 90.16% of the cases with Rb tumor showed evidence of calcification on CT scam.The contrast enhancement of the tumor was slight.19.67% of the cases with Rb tumor showed retrobulbar extension and invaded intracranium(in- cluding 3 cases of intracranical trmor extension and one case of trilateral Rb).We think it is important to perform CT scan in suspected cases of Rb,and in patients with Rb invading the orbit or intracranium as well as in bilateral Rb.Some problems in the diagnosis and differential diagnosis are briefly dissussed.
