目的探讨眶内疾病所致眼球突出CT影像及临床特点,提高原发性眼眶炎性假瘤、格氏眼病、眼眶内肿物等所致眼球突出的诊断及鉴别诊断。方法回顾性分析94例经临床、手术及病理明确诊断的眶内疾病致眼球突出CT影像及临床表现,观察眼肌、视神经、泪腺等眼眶内组织结构及肿块形态、大小、密度改变。结果51例原发性眼眶炎性假瘤CT显示单侧眼外肌肿胀增粗、泪腺增大、眼眶内肿块及球后脂肪间隙密度不均。31例格氏眼病CT主要表现为双侧多条眼外肌肌腹梭形肥大,视神经增粗,眼肌边缘光滑,眶内脂肪增多,密度均匀。12例为邻近器官肿块入侵眼眶及眶内原发肿瘤。结论诊断眼眶炎性假瘤,CT表现是主要依据,不典型表现需结合临床或做其他影像学检查。常需与格氏眼病、眶内肿瘤等疾病鉴别。
Objective To investigate the CT features and clinical features of orbital diseases caused by orbital diseases and to improve the diagnosis and differential diagnosis of prominent ocular protrusion caused by primary orbital inflammatory pseudotumor, Grignard disease or orbital tumor. Methods Retrospective analysis of 94 cases of orbital diseases diagnosed by clinical, surgical and pathological diagnosis of prominent ocular CT images and clinical manifestations observed eye tissue, optic nerve, lacrimal gland and other orbital tissue structure and mass morphology, size, density changes. Results 51 cases of primary orbital inflammatory pseudotumor CT showed unilateral extraocular muscle swelling and thickening, lacrimal gland enlargement, orbital mass and posterior ball fat gap density. 31 cases of Keynes disease CT mainly manifested as bilateral multiple extraocular muscle spine fusiform hypertrophy, optic nerve thickening, ophthalmic muscle smooth, orbital fat increased, uniform density. 12 cases of adjacent organ tumor invasion of orbital and orbital primary tumor. Conclusion The diagnosis of orbital inflammatory pseudotumor, CT performance is the main basis for atypical manifestations need to be combined with clinical or other imaging examination. Often need and Grignard disease, orbital tumors and other diseases identified.
