42例眼眶炎性假瘤临床及影像学分析

目的通过分析总结眼眶炎性假瘤临床和影像学特点,提高该病诊断水平.方法经手术病理或临床治疗观察确诊的眼眶炎性假瘤42例,回顾分析其临床及CT、MRI表现.结果42例中,以突眼(占73.8%)及眼球运动障碍(占52.4%)为主要表现,其次为眼缘触及肿块(占40.5%);其中单眼发病33例,双侧发病9例.CT分型:浅层巩膜型2例,浸润型4例,肿块型13例,肌炎型11例,泪腺型12例;MRI检查11例,其分型及表现基本同CT扫描.结论CT、MRI能明确眼眶炎性假瘤的部位及侵犯范围,其分型为临床确定治疗方案提供重要依据.

Clinical and imaging analysis of 42 cases of orbital inflammatory pseudotumor

Objective:To understand the clinical and imaging features of inflammatory orbital pseudotu-mor,thus to improve the diagnostic threshold of this disease.Methods:Clinical,CT and MRI data of42cases of inflammatory pseudotumor were collected and analyzed.Results:Of the42cases,ocular proptosis was the most common manifestation(73.8%),followed by motility restriction(52.4%)and palpable mass(40.5%).Among them,single eye involvement occurred in33cases,and both eyes involvement in9cases.According to CT features,focal mass within orbit was the most seen subtype in4cases,followed by lacrimal inflammatory pseudotumor in13cases,myositis in11cases,diffuse orbital inflammatory pseudotumor in12cases and episcleritis in2cases.MRI examination was performed in11cases,and revealed the results of clinical signs and subtypes similar to those of the CT scan revealed.Conclusions:CT scan and MRI can demonstrate the location and extent of orbital inflammatory pseudotumor,thus definite the subtype and furnish the basis for a therapy regiment.
