目的:探讨眼眶炎性假瘤的临床—影像诊断与鉴别诊断。方法:回顾性分析25例临床资料较完整并经临床—影像和病理证实。男性15例,女性10例。结果:25倒依据炎症的解剖部位分为五组,①单一泪腺受累,合并其它眼眶内组织改变;②眼肌受累,单一,多发性常合并眶内脂肪浸涧;③眶内脂肪受累,弥漫性界限不清的浸润,合并或不合并视神经、泪腺和肌肉受累,肿块形成;④眶尖的浸润或肿块;⑤眼球受累。结论:临床——影像表现结合,诊断不困难。如缺乏特征性者,需活检,并和其它疾病作鉴别。 Objective: To investigate the clinical-imaging diagnosis and differential diagnosis of orbital inflammatory pseudotumor. Methods: Retrospective analysis of 25 cases of clinical data more complete and confirmed by clinical - imaging and pathology. 15 males and 10 females. Results: 25 down according to the anatomy of inflammation is divided into five groups, ① a single lacrimal gland involvement, combined with other orbital tissue changes; ② oculomotor involvement, single, multiple and often infiltration of orbital fat; ③ orbital fat involvement, diffuse Imperceptible infiltration of the boundaries, with or without optic nerve, lacrimal gland and muscle involvement, the formation of lumps; orbital apex infiltration or mass; ⑤ eye involvement. Conclusion: The combination of clinical and imaging findings is not difficult to diagnose. Such as the lack of characteristic, biopsy, and identification of other diseases.
