Prpose : To study the MR findings to predict the site of dural attachment in meningiomas. Materials andMethods : We retrospectively reviewed MR findings of 23 patients with surgically confirmed meningiomas andanalysed the characteristics of dural attachment site of meningiomas and tumor growing vector against dura.Results : In the 10 cases that tumor had a single dural base, the dural base was tumor bed. In the 2 cases thattumor had more than two dural bases, wider, irregular and thicker enhancing dura was tumor bed. In the 7 of the 11cases of diffuse dural bases with tumor, we could predict tumor bed considering the degree of compression to thebrain parenchyma and the tumor growing vector. Conclusions : In the case of tumor having more than two surfacescontacting the dura or with narrow attachment site, it is possible to predict the site of dural attachment if weconsider the characteristrics of dural attachment site and tumor growing vector against dura.
