摘　　要：目的探讨后颅窝原发性脑膜黑色素细胞瘤的临床表现、影像学特点与治疗经验。方法回顾分析1例经病理学检查诊断为后颅窝原发性脑膜黑色素细胞瘤的临床病例,结合国内外相关文献总结后颅窝原发性脑膜黑色素细胞瘤的临床表现、影像学特点。结果手术全切1例后颅窝原发性脑膜黑色素细胞瘤,随访未见肿瘤复发及转移。结论后颅窝原发性脑膜黑色素细胞瘤临床少见,其磁共振成像(magnetic resonance imaging,MRI)影像学具有特征性,术前可做出明确诊断。Objective To investigate the clinical manifestations,imaging features and treatment experience of primary meningeal melanocytoma.Methods A retrospective analysis of a clinical case of primary meningeal melanocytoma.Pathology diagnosed was performed.The clinical manifestations and imaging features of intracranial primary meningeal melanocytoma were summarized based on relevant domestic and international literature.Results Primary meningeal melanoma was completely resected.No recurrence or metastasis was found during follow-up.Conclusion The posterior cranial fossa primary melanocytoma is rarely seen clinically,and it has characteristic magnetic resonance imaging(MRI)features.Posterior cranial fossa primary meningeal melanoma can be diagnosed before surgery.
