【摘要】 目的　探讨颅底脑膜瘤骨增生与骨侵袭的关系。方法　选取 6 0例需手术治疗的颅底脑膜瘤患者 ,术前均行CT检查 ,确定骨质增生的程度与部位 ;术中将肿瘤连同骨质增生进行病理检查 ,确定有无脑膜瘤细胞骨侵袭。结果　CT证实的 34例有骨增生的颅底脑膜瘤患者 ,进行增生骨质活检有肿瘤细胞侵袭者 31例。结论　颅底脑膜瘤骨增生与肿瘤细胞骨侵袭有关 ,手术时应予充分切除。更多还原

【Abstract】 Objective To investigate the hyperostotic changes in meningioma of the cranial base associated with tumor invasion. Methods 60 patients underwent resection for meningioma involving the cranial base. Preoperative radiographic evaluation using computed tomography (CT) was performed, and areas of hyperostosis were identified. During the resection of the tumor, biopsies from these hyperostotic regions were sent for histological evaluation regarding the presence or absence of tumor invasion of the bone. Results Preoperative neuroradiological assessment by CT identified 34 patients with radiographic evidence of hyperostosis. Histological examination of the resected bone showed tumor invasion in 31 patients.Conclusion Hyperostotic changes in meningioma of the cranial base are caused by tumor invasion of the bone histologically.更多还原
