目的：总结分析眼眶炎性假瘤的ＣＴ表现，并对眼眶假瘤的ＣＴ分型进行探讨。材料与方法：回顾性分析我院１０年间资料完整的眼眶假瘤４６例。结果：泪腺炎型１５例，７例双侧泪腺增大，８例单侧增大，密度均匀，边界清楚；前部假瘤５例，位于眼球后方，与眼球紧贴，边缘不清楚，密度不均，２例伴眼外肌增粗，１例伴视网膜脱落；后部假瘤６例，位于眶尖部，不规则，密度不均，沿视神经及眼外肌向前发展；弥漫型６例，充满眶内球后区，密度不均，眶内结构分界不清；肌炎型１４例，单侧发病，累及一或两条肌肉，弥漫性增粗。结论：ＣＴ能明确病变部位、范围和对炎性假瘤的分型，并能跟踪观察疾病过程及评价治疗效果
Objective: To summarize and analyze the CT manifestations of orbital inflammatory pseudotumor, and discuss the CT classification of orbital pseudotumor. Materials and Methods: A retrospective analysis of our hospital 10 years orbital integrity of 46 cases of orbital pseudotumor. Results: 15 cases of lacrimal gland inflammation, 7 cases of bilateral lacrimal gland enlargement, 8 cases of unilateral increase, uniform density, clear boundary; anterior pseudotumor in 5 cases, located in the back of the eyeball, close to the eyeball, the edge is not clear, the density 2 cases with extraocular muscle thickening, 1 case with retinal detachment; 6 posterior pseudotumor, located in the orbital apex, irregular, uneven density, along the optic nerve and extraocular muscles forward; diffuse 6 Cases, filled with orbital sphere, uneven density, orbital structure of the boundary is unclear; myositis in 14 cases, unilateral disease, involving one or two muscles, diffuse thickening. Conclusion: CT can identify the lesion, extent and types of inflammatory pseudotumor, and can follow the process of disease observation and evaluation of the treatment effect
