【摘要】 目的 探讨颅眶沟通性脑膜瘤的临床、病理及影像学(CT和MRI)特征。方法 回顾性分析经手术病理证实且资料齐全的颅眶沟通性脑膜瘤13例,分析其CT和MRI影像特征,重点观察肿瘤的形态、大小、边界、肿瘤基底宽度、瘤周水肿宽度、强化均匀程度以及脑膜尾征长度等,观察指标经量化处理,并随机抽取临床、影像资料齐全并经病理证实的颅内脑膜瘤29例,对比分析2组病例的临床、病理及影像特征差异。结果 13例颅眶沟通性脑膜瘤临床主要表现为头痛、突眼、视力减退、眼球运动受限、视乳头水肿等症状,形态以哑铃状多见,肿瘤最大径平均值、肿瘤基底最大宽度平均值、瘤周水肿最大宽度平均值、脑膜尾征邻近强化硬脑膜的最大长度平均值均大于颅内脑膜瘤(P<0.05)。结论 颅眶沟通性脑膜瘤具有一定的临床、病理及CT、MRI表现特征。更多还原

【Abstract】 Objective To investigate the clinic,pathology and imaging(CT and MRI) features of cranio-orbital communicating meningioma.Methods 13 patients with cranio-orbital communicating meningiomas proved by pathology were analyzed.The CT and MRI features including the tumor shape,size,borders,tumor base width,the width of edema,the enhancement after contrast medium administration and the length of dural tail sign were analyzed and compared with those of intracranial meningiomas in 29 cases.Results Of 13 cases,the clinical features included headache,exophthalmos,visual deterioration,congestion of conjunctiva and papilledema and so on.Most cranio-orbital communicating meningiomas were dumbbell.The average size,basalis width,dural tail sign’s length,brain edema around the tumor in cranio-orbital communicating meningiomas were obvious compared with those of intracranial meningiomas(P<0.05).Conclusion The cranio-orbital communicating meningiomas have certain clinic,CT and MR characteristics.更多还原
