目的探讨枕骨大孔区肿瘤的临床和MRI诊断特点.方法对52例经病理证实的枕骨大孔区肿瘤患者的临床和MRI表现进行回顾性分析,并复习相关文献.结果室管膜瘤9例,主要发生于40岁以后,有囊变,实质部分强化显著,囊性部分不强化,境界清楚；脑膜瘤10例,宽基底,增强有明显相对均一强化,且有硬膜尾征；血管母细胞瘤7例,以青壮年多见,呈大囊小结节,增强壁结节明显强化,囊性部分不强化为特点；髓母细胞瘤8例,多位于小脑,信号欠均匀,强化显著,DWI为高信号；脊索瘤6例,多位于鞍背,信号不均,并有骨质破坏；神经鞘瘤12例,多沿神经走行,强化明显.结论枕骨大孔区各种肿瘤MRI特点具有一定特征性,对定性诊断有较高的临床价值.

Objective To study the clinical features and MRI appearances of the tumors in the region of foramen magnum.Methods The clinical and MRI findings of 52 patients with tumors in the foramen magnum by pathologically confirmed were analyzed retrospectively with literatures review.Results Ependymoma(9 cases),occurring mainly after the age of 40,there was cystic change,the real part of the enhanced significantly,cystic partially enhanced,state clearly.Meningioma(10 cases),wide base and enhance significant relatively homogeneous enhancement and dural tail sign there.Hemangioblastomas (7 cases),more common in young adults,showed a large cystic nodules,increased mural nodules was significantly enhanced,cystic partially characterized enhancement.Medulloblastoma (8 cases),almost were located in the cerebellum,the signal was uniform,and strengthen significant,DWI high signal.Chordoma(6 cases),and more back in the saddle,the signal uneven and bone destruction.Nerve sheath tumor(12 cases),and always traveling along the nerve with marked enhancement.Conclusions MRI imagining of the tumors in the region of foramen magnum have certain charactteristic,it has significant value in diagnosing for clinical to nature of disease.
