Meningiomas are extraaxial tumors that arise from the arachnoid layer of the meninges. Seizures are the most common clinical sign in dogs; cats more often present with mentation changes, vision loss, and gait abnormalities. Meningiomas in both species grow slowly and have an insidious onset of clinical signs. These tumors are more likely to be malignant in dogs. Surgery, radiation, and chemotherapy can target the primary tumor, whereas steroids and anticonvulsants are confined to treating secondary effects of the tumor. Surgery is the preferred primary option for cats because the tumor can be excised completely in most cases. If the meningioma cannot be resected in its entirety, radiation therapy can increase survival time.
脑膜瘤是起源于脑膜蛛网膜层的轴外肿瘤。癫痫发作是犬类最常见的临床症状；猫更常表现为精神状态改变、视力丧失和步态异常。这两个物种的脑膜瘤生长缓慢，临床症状隐匿。这些肿瘤在犬类中更有可能是恶性的。手术、放疗和化疗可针对原发性肿瘤，而类固醇和抗惊厥药则仅限于治疗肿瘤的继发效应。手术是猫的首选主要治疗方法，因为在大多数情况下肿瘤可以完全切除。如果脑膜瘤不能完全切除，放射治疗可以延长生存时间。
