摘　　要：目的:探讨MRI对于眶颅沟通肿瘤的诊断及应用价值。方法:回顾分析10例眶颅沟通肿瘤的MRI影像学表现。结果:共发现眶颅交通肿瘤共10例。其中神经鞘瘤1例,表现囊实性肿块,经视神经孔延伸至海绵窦旁;炎性假瘤3例,表现片块状、境界不清肿块影,其中2例经眶上裂延伸至海绵窦旁,侵犯同侧颞叶,1例经视神经管、眶上裂进入,延伸至海绵窦,侵犯视交叉和颞叶;腺样囊性癌2例,表现片块状不规则肿块影,经眶上裂延伸海绵窦、颞叶、颞下窝及翼腭窝;混合性生殖细胞瘤1例,表现为卵圆形软组织肿块影,直接破坏骨壁,侵犯额叶;胚胎性横纹肌肉瘤复发1例,表现不规则软组织肿块影,经视神经管、眶上裂进入,延伸至海绵窦,侵犯视交叉和颞叶;骨母细胞瘤样骨肉瘤伴动脉瘤样骨囊肿1例,表现为眼眶上壁骨质破坏,直接破坏骨壁,侵犯额叶。结论:MRI检查可以明确眶颅沟通肿瘤的部位、性质及周围侵犯情况,对于眶颅沟通肿瘤的手术方法选择具有重要参考价值。Objective To evaluate the diagnostic value of magnetic resonance imaging(MRI)in orbito-cranial communicating tumors.Methods To review and analyze MRI imaging representation of 10 patients within orbito-cranial communicating tumors confirmed by surgical pathology or follow-up were retrospectively analyze.Results Total 10 cases of orbito-cranial communicating tumors.In these cases,1 case of schwannoma,showed cystic or solid mass,via optic Kong Yanshen to next to the cavernous sinus;Inflammatory pseudotumor in 3,performance piece block,the boundary is not clear the lump,among them 2 cases via supraorbital fissure extends to the cavernous sinus,infringement of ipsilateral temporal lobe,1 case of the optic canal,supraorbital fissure,extends to the cavernous sinus,infringement of optic chiasma and temporal lobe;Adenoid cystic carcinoma in 2 cases,performance piece lump haphazard mass shadow,via supraorbital fissure extension under the cavernous sinus,temporal lobe,temporal fossa and wing palatine nest;Mixed germ cell tumor in 1 case,characterized by ovoid soft-tissue mass shadow,destroy the bone wall directly,infringement of the frontal lobes;Embryonal rhabdomyosarcoma in 1 case of recurrence and irregular soft tissue mass,the optic canal,supraorbital fissure,extends to the cavernous sinus,infringement of optic chiasma and temporal lobe;Bone tumor samples with osteosarcoma aneurysm sample bone cyst in 1 case,performance for orbital wall bone destruction,destruction of bone wall directly,infringement of the frontal lobes.Conclusion Cranial MRI examination can clearly communicate orbital tumors location,nature and circumstances surrounding violations,for orbital tumors cranial surgery Methods of communication have important reference value.
