对经手术病理证实和临床确诊的95例眼眶及眶周占位病变致突眼患者的CT征象作回顾性分析。结果发现，导致突眼的占位病变以炎性假酒和血管性病变居多，各26例，其余依次为鼻窦占位病变13例，视神经鞘膜瘤和脑膜后各7例，泪囊、泪腺占位和转移瘤各6例，脓肿、血肿4例。CT检查对炎性假瘤、血管病变、单纯性泪囊和泪腺病变、视神经鞘膜瘤、脑膜瘤等具有较典型CT征象的多数病变，结合临床能作出明确定性诊断，对少数鼻窦占垃病变，尤其是转移瘤定性诊断仍有困难。
A retrospective analysis of the CT signs of surgically pathologically confirmed and clinically confirmed 95 cases of eyelids and peripheral orbital lesions caused by exophthalmos was performed. The results showed that the occupying lesions of the exophthalmos were mostly inflammatory pseudo-alcoholic and vascular lesions, with 26 cases in each, followed by 13 cases of sinus space occupying lesions, 7 cases of optic nerve sheath tumors and 7 cases of meningeal septum, and lacrimal sac and lacrimal gland. There were 6 cases of occupying and metastasis, 4 cases of abscess and hematoma. CT examination of inflammatory pseudotumor, vascular lesions, simple lacrimal sac and lacrimal gland lesions, optic nerve sheath tumor, meningioma, etc. have more typical CT signs of lesions, combined with clinical can make a clear diagnosis, a small number of sinus lesions In particular, the qualitative diagnosis of metastases remains difficult.
