摘要
目的分析急性眼眶炎性病变的CT、MRI表现并探讨其临床价值。方法回顾总结40例眼眶炎性病变患者的CT、MRI征象。眼眶CT、MRI检查12例,仅行眼眶CT检查28例。结果按病因分类:鼻窦源性22例,外伤源性12例,肝克雷伯杆菌感染2例,糖尿病4例。按累及结构分类:骨膜下脓肿形成5例,肌锥内间隙脓肿1例,肌锥外间隙炎症4例,眶隔前炎症3例,海绵窦炎3例,弥漫性炎症7例,内源性眼内炎3例,眼球筋膜炎5例,泪囊炎2例,泪腺炎7例。眼眶炎症影像特点取决于受累结构及范围,表现为眶内正常结构界面消失和一个或多个解剖间隙局限或弥漫浸润。结论 CT、MRI对客观显示眼眶炎症的致病原因和累及范围具有重要价值。
Objective To analyze CT and MR manifestations of acute orbital inflammatory lesions and to discuss their clinical values. Methods CT and MRI findings in 40 patients with acute orbital inflammatory lesions （50 diseased eyes in total） were retrospectively analyzed. The patients included 24 males and 16 females. Both orbital CT and MRI scans were performed in 12 cases, and only orbital CT scan was employed in 28 cases. Results According to the etiology, the orbital lesions were caused by paranasal origin （n = 22） , traumatic origin （n = 12） , Klebsiella infection of the liver （n = 2） and diabetes mellitus （n = 4）. Based on the involved structures, the lesions included sub-periosteal abscess （ n = 1 ） , muscle intra-eone space abscess （ n = 1 ） , extra-tonal space inflammation （ n = 4） , inflammation anterior to orbital septum （ n = 3 ） , inflammation of cavernous sinus （ n = 3 ） , diffuse inflammation （ n = 7 ） , endogenous endophthalmitis （ n = 3 ） , eyeball fasciitis （ n = 5 ） , dacl：cocystitis （ n = 2） and lacrimal gland inflammation （ n = 7 ）. The imaging characteristics of orbital inflammation depended on the involved structures and extent. Usually, the orbital inflammation was characterized by disappearance of intra-orbital normal structural interface, and localized or diffuse infiltration within one or more anatomic spaces. Conclusion For acute orbital inflammatory lesions, CT and MRI examinations are of great value in verifying the etiology and in displaying the involved extent.
