起源于自主神经节的神经源性肿瘤包括神经节瘤、成神经节细胞瘤和成神经细胞瘤。神经节瘤是良性的,而成神经细胞瘤是儿童中常见的高度恶性肿瘤。成神经节细胞瘤被认为具有低度恶性,介于神经节瘤和成神经细胞瘤之间。大约25％的神经节瘤并非完全良性,而是包含低分化成份。神经节瘤诊断的难点可能在于过分依赖也许仅代表病变一小部分的 Neurogenic tumors that originate in autonomic ganglia include gangliomas, ganglioneuromas and neuroblastomas. Ganglioma is benign, and neuroblastoma is a common high-grade tumor in children. Ganglioneuroma is considered to have a low degree of malignancy, between the ganglioneuroma and neuroblastoma. About 25% of gangliomas are not completely benign but contain poorly differentiated components. The crux of the diagnosis of gangliomas may be over-reliance may represent only a small part of the lesion
