摘要
目的探讨累及眼环的眼眶病变CT征象的鉴别点。资料与方法分析60例67眼累及眼环的眼眶病变的CT征象,行两个相关样本率比较χ2检验及双向无序分类资料的关联性检验。结果 (1)18例眼球内病变主体均位于眼环内侧。(2)良性肿瘤和炎性病变一定位于眼环的一侧,而恶性肿瘤可位于眼环两侧。且病变的性质与其位于眼环内外侧有关联性(P=0.001及C=0.438)。(3)良性肿瘤多与眼环成锐角,而炎性病变和恶性肿瘤一定与眼环成钝角,且病变的性质和其与眼环的夹角具有关联性(P=0.000及C=0.759)。结论 (1)球内病变主体多位于眼环内侧。(2)球外病变中良性肿瘤多与眼环成锐角;炎性病变及恶性肿瘤与眼环成钝角,而后者可侵及眼环内侧。
Objective To evaluate the various CT features in different orbit diseases invasion to eyeballs.Materials and Methods The CT features of 60 cases including 67 eyes of orbit diseases invasion to eyeballs confirmed by operation and/or pathology were studied.Related-samples Chi-squaer test and bidirectional disorder grouped data correletion test were calculated.Results（1）Eighteen cases of orbit lesions invaded the inner side of the eyeballs.（2） Benign tumors and inflammatory lesions involved one side of the eyeballs,while malignant tumours could involve two sides of the eyeballs.It had relevance between the nature of lesions and the locations（P=0.001 and C=0.438）.（3）There was always an acute angle between benign lesion and eyeball,and an obtuse angle between inflammatory lesion or malignant tumour and eyeball（P=0.000 and C=0.759）.Conclusion（1） The orbit lesions mostly involved the inner side of the eyeball.（2） There is always an acute angle between benign lesion and eyeball,and an obtuse angle between inflammatory lesion or malignant tumour and eyeball,otherwise malignant tumours could invloved two sides of the eyeballs.
