目的:探讨CT对泪腺良性肿瘤的诊断价值。方法:回顾性分析30例经病理证实良性泪腺肿瘤临床资料和CT影像资料。结果:泪腺良性肿瘤患者30例中26例位于泪腺眶部,泪腺睑部4例。肿瘤椭圆形18例,不规则形4例,边缘不规则呈现分叶状或结节状8例。CT表现大多数为密度均匀,眼眶皮质受压,凹陷18例,骨皮质破坏伴硬化肥厚12例。结论:泪腺良性肿瘤CT有一定特征,诊断准确率高。

·AIM:To discuss the value of CT in diagnosing benign tumor of the lacrimal gland.·METHODS:The clinical data and imaging manifesta-tions of 30 cases with pathologically confirmed benign lacrimal gland tumor were analyzed retrospectively.·RESULTS:The lesions originated in the orbital lobe of the lacrimal gland in 26 cases and the palpebral lobe in 4 cases.The tumors showed oval shape in 18 cases,irregular shape in 4 cases,irregular margin shape in 8 cases.Most cases showed average density on CT.Orbital bone compression or defect was seen in 18 cases,bone destruction with hyperostosis bone sclerosis in 12 cases.·CONCLUSION:Benign tumos in the lacrimal gland have some imaging features.·
