Meningiomas are the most common primary brain tumor and their incidence and prevalence is increasing. This review summarizes current evidence regarding the embryogenesis of the human meninges in the context of meningioma pathogenesis and anatomical distribution. Though not mutually exclusive, chromosomal instability and pathogenic variants affecting the long arm of chromosome 22 (22q) result in meningiomas in neural-crest cell-derived meninges, while variants affecting Hedgehog signaling, PI3K signaling, TRAF7, KLF4, and POLR2A result in meningiomas in the mesodermal-derived meninges of the midline and paramedian anterior, central, and ventral posterior skull base. Current evidence regarding the common pathways for genetic pathogenesis and the anatomical distribution of meningiomas is presented alongside existing understanding of the embryological origins for the meninges prior to proposing next steps for this work.
脑膜瘤是最常见的原发性脑肿瘤,其发病率和患病率正在增加。本综述总结了当前关于人类脑膜在脑膜瘤发病机制和解剖分布背景下的胚胎发生的证据。虽然并非相互排斥,但染色体不稳定性和影响 22 号染色体长臂(22q)的致病变体导致源自神经嵴细胞的脑膜瘤,而影响 Hedgehog 信号、PI3K 信号、TRAF7、KLF4 和 POLR2A 的变体导致源自中线和旁正中前、中央和颅底后腹侧的中胚层衍生脑膜的脑膜瘤。本文在提出这项工作的下一步之前,提出了遗传发病机制的常见途径和脑膜瘤解剖分布的当前证据,以及对脑膜胚胎起源的现有认识。
