Abstract

Background: Meningioma, a common and mostly benign intracranial and spinal tumor, can coexist with other malignant tumors. Such a scenario is very rare in patients with no history of radiation therapy or phakomatosis. In this study, the authors present three cases of concurrent/adjacent CNS tumors, review the literature on this topic, and highlight some genomic alterations in that regard.

Observations: The authors present three cases of patients who had coexistence of meningioma with other glial tumors in this study.

Lessons: Coexistence/collision of intracranial and spinal meningiomas with another CNS pathology occurs anecdotally. This phenomenon does not necessarily preclude resection of both tumors in a single session, provided that a careful preoperative assessment of the surgical anatomy is undertaken. Conducting studies to evaluate the genomic structures of such cases and to explain why they occur in adjacency could be valuable in explaining this phenomenon. https://thejns.org/doi/10.3171/CASE24805.

无综合征性相邻/碰撞性脑膜瘤并发神经胶质肿瘤：说明性病例。

背景：脑膜瘤是一种常见的颅内和脊柱良性肿瘤，可与其他恶性肿瘤并存。这种情况在没有放射治疗史或噬瘤病史的患者中非常罕见。在本研究中，作者介绍了三例并发/相邻中枢神经系统肿瘤的病例，回顾了有关这一主题的文献，并强调了这方面的一些基因组改变：作者在本研究中介绍了三例脑膜瘤与其他胶质瘤并存的患者：启示：颅内和脊柱脑膜瘤与其他中枢神经系统病变并存/冲突的情况时有发生。只要术前对手术解剖进行了仔细评估，这种现象并不一定不能在一次手术中切除这两种肿瘤。开展研究以评估此类病例的基因组结构，并解释它们为什么会发生相邻关系，这对解释这种现象很有价值。https://thejns.org/doi/10.3171/CASE24805。
