Abstract:ObjectiveTo investigate the clinical manifestations,diagnosis,pathogenesis,and treatment of primary intracranialcolision tumors.MethodsThe clinical dataofone patientwith primary intracranialcolision tumor treated inthe Departmentof Neurosurgery,Lianyungang First People's Hospital were analyzed retrospectively. The relevant literaturewerereviewed.Thesurgerywasperformed viaamodifiedpterional approach toresect the intracranial mass,andpostoperativeadjuvantradiochemotherapy wasadministered according tothe STUPP protocol. ResultsThe patient presented with dizziness,headache withnausea andvomiting for3days.MRI showed the presence of meningiomaand glioblastoma(GBM)in adjacent regions of the left cerebral hemisphere.Postoperative pathology confirmed meningioma(WHO GradeI)and GBM(WHO Grade IV).MRI examination at the8-month follow-up showed that the tumorrecurredattheoriginal site.ConclusionsIntracranial collsion tumorsare often composed of meningioma and GBM. Clinical manifestations and imaging findings lack specificity,and the etiology is complex,involvinggenetic,environmental,andimmunological factors.Furtherresearch isneededtoclarifytheir natural course and exact mechanisms and to explore more effective treatment strategies.

顱內碰撞腫瘤代表在同一腦區出現兩種組織學上不同的原發腫瘤,這種情況臨床罕見[1]。有報道[1]指出,顱內碰撞瘤中最常見的是腦膜瘤和腦膠質母細胞瘤(glioblastoma,GBM)。腦膠質瘤是成年人中最常見的中樞神經系統惡性腫瘤[2],占全部顱內腫瘤的
;其中約有 75% 為高級別膠質瘤(high-gradeglioma,HGG),以GBM最為常見,每年的發病率約為3.1/10萬[3]。盡管有手術、放療、化療等標準化的綜合治療,但其預后仍然較差,5年生存率低于
。腦膜瘤的發病率為每 6/10 萬,占所有顱內腫瘤的
。目前,腦腫瘤的病理診斷標準采用的是世界衛生組織(WorldHealthOrganization,WHO)中樞神經系統(centralnervoussystem,CNS)腫瘤分類,根據第五版腫瘤分類,腫瘤的病理分級采用了I-V級的分型系統,級別越高,表示腫瘤的惡性程度越高[。GBM為V級,而 80% 以上的腦膜瘤為I級腫瘤,提示臨床病程為良性,預后良好;只有少數腦膜瘤預后較差,包括間變性腦膜瘤和腦膜肉瘤等[6-8]。本研究納入連云港市第一人民醫院神經外科收治的1例顱內原發性碰撞瘤患者,現報告如下。
1資料與方法
1.1一般資料患者女性,57歲,因\"頭暈、頭痛伴惡心嘔吐3d\"于2023年10月16日收入連云港市第一人民醫院。
入院前3d起出現頭暈,昏沉感,伴頭痛,左側額頂部明顯,伴惡心、嘔吐,嘔吐胃內容物數次。入院后追問病史,患者自訴3年前于外院診斷為腦膜瘤,定期復查,未見詳細報告。既往無頭部外傷史、無神經系統手術及放療史。神經系統查體未見特殊異常。頭顱核磁共振成像(magneticresonanceimaging,MRI)檢查提示左額葉見團塊狀混雜信號,增強后腫瘤實體由兩部分組成,一部分呈不均勻花環樣強化,另一部分基底較寬,密度均勻一致,“腦膜尾征”陽性。……
