概述

室管膜瘤是一种在脑或脊髓中形成的细胞生长物。这些细胞会形成一个肿块,称为肿瘤。室管膜瘤始于室管膜细胞。这些细胞构成了脑脊液流动通道的内衬层。脑脊液包围并保护着脑和脊髓。

室管膜瘤有多种不同的类型。有的生长缓慢,不被认为是癌性肿瘤。非癌性肿瘤也称为良性肿瘤。良性室管膜瘤的生长可能会压迫邻近的组织。有时室管膜瘤生长更为迅速,被认为是癌性肿瘤。癌性肿瘤也称为恶性肿瘤。恶性室管膜瘤的生长可能会侵袭并破坏邻近组织。癌细胞可能会脱落并在脑或脊髓内扩散。

室管膜瘤可能发生在任何年龄段,但在幼儿中最为常见。患有室管膜瘤的儿童可能会出现头痛和癫痫发作。发生在成人体内的室管膜瘤更有可能在脊髓中形成。这可能导致受肿瘤影响的神经所控制的身体部位无力。

外科手术是室管膜瘤的主要治疗方法。对于生长迅速的肿瘤或手术无法完全切除的肿瘤,可能建议采取其他治疗方法。其中可能包括放射疗法、放射外科手术、化疗或靶向治疗。
