摘要
继发性眼眶肿瘤引起眼球突出,根据病史、年龄、眼部及相关部位(耳鼻颅脑等)的改变,结合超声、X 线或眼眶造影等检查,大部分可以做出病因诊断。随着CT 的广泛应用,使眼球突出的病因诊断变得更加容易准确。有关鼻窦肿瘤侵犯眶内的CT 表现报导很少,我院自86年～90年间共诊治10例,现报告分析如下。临床资料本组10例诊断均经手术和病理证实,所用CT 为日本产日立W4型第三代扫描机,常规采用水平层面,对可疑颅内沟通者辅以冠状扫描层面3～5mm,窗宽100～500H,观察骨改变时用1000～2000H。
Analysis of computed tomography(CT)scans in 10 pathologically proved cases of
prominace of eye caused by the tumors of paranasal sinus were carried out in this study.For
the purposes of comparison plain films of these 10 cases were also studied.CT could provide
paranasal sinus and orbit more clearly than plain film.All these data could be effective
evidences for the etiological diagnosis of the prominance of eye caused by the tumors of
paranasal sinus.This information give help to the selection of best scheme which includes
selection of the surgical approach,definition of the irradiation fields and evalution of tumor
response when cbemotheraphy is employed.
