| 摘 要： | 目的探讨侵袭性脑膜瘤的MRI表现。方法回顾性分析23例经手术病理证实的侵袭性脑膜瘤的MRI及临床表现。结果3例脑侵袭,肿瘤边界毛糙模糊,边界棘状突起及蘑菇征;15例硬脑膜侵犯,脑膜尾征明显延长大于3cm并结节状改变;12例蛛网膜侵犯,蛛网膜增厚,脑脊液-血管间隙消失;2例骨骼、肌肉受侵犯,颅骨内外板破坏,呈不规则异常信号,邻近肌肉隆起呈结节状。结论MRI可显示侵袭性脑膜瘤的侵袭性特点,为制定手术方案提供依据。

| Abstract: | Objective:To explore MRI findings of invasive meningioma.Methods:23 cases of MR of invasive meningioma proved by operative pathology were analyzed retrospectively.Results:3 cases of brains was invaded. The edge of tumor is rough and illegible,and has protuberance like thorn and fungus;15 cases of duramater invaded. The end of meninges extended distinctly over 3cm and changed like knots;12 cases of arachnoids invaded. Arachnoids thickened,the space between succus and blood vessel disappeared;2 cases of skeleton and muscl invaded. The skull damaged showed abnormal signal and the adjacent muscle has apophysis like knots.Conclusion:MR can show meningioma invaded and set down the theropy. |
