摘要
目的报告1例罕见的侧脑室内胶质瘤与脑膜瘤的碰撞瘤，并探讨其发生原因。方法39岁男性，6年前曾行侧脑室内胶质瘤切除术；此次以头痛及头晕发病，MRI示胶质瘤原位复发，且同时合并另一占位性病变，予以手术切除。术后病理证实为胶质瘤与脑膜瘤的碰撞瘤；本文同时也对这种碰撞瘤进行文献复习。结果术后患者恢复满意，并行伽玛刀放射治疗，随访1年时患者状态良好。本文在复习侧脑室内胶质瘤与脑膜瘤的碰撞瘤发生原因后，总结了几种假设。结论复发的胶质瘤诱发脉络丛内的蛛网膜细胞恶性转化可能是导致脑膜瘤的原因，同时胶质瘤的刺激也可能诱导了脑膜瘤的生长。
Objective To report one case of a collision tumor composed of intraventricular meningioma and astrocytoma and explore the cause. Methods A 39 - year - old male patient previously underwent excision of astrocytoma in the triangle area of the lateral ventricle and had good postsurgery recovery. The astrocytoma recurred in situ 6 years after the surgery, and it was also complicated with another lesion. The pathological results confirmed a collision tumor composed of intraventricular malignant meningioma and glioma. In addition to reporting this case, we also performed a literature review of collision tumors. Results The patient recovered well after surgery to treat the recurrence and was given radiotherapy after discharge. Based on this literature review, we proposed several hypotheses on the formation of collision tumors. Conclusions We conclude that one possible reason of the collision tumor formed between the intracranial meningioma and the astrocytoma was the recurrence of astrocytoma - induced malignancy of arachnoid cells in the choroid plexus.
