Central nervous system (CNS) tumors are the most common solid neoplasms in childhood and the second most common malignancies after leukemia in the pediatric age group. Supratentorial tumors are more common in children younger than 2 years old and in adolescents, whereas in patients between 2 and 12 years of age brain tumors originating in the posterior fossa dominate. This implies a relationship between the type of tumor, its location and the age of the patient, which has to be considered in differential diagnoses. Medulloblastoma represents the most common malignant brain tumor in childhood. In the posterior fossa medulloblastomas are approximately as frequent as astrocytomas. Supratentorial astrocytomas are by far the main tumor type. In this report some typical CNS neoplasms in children are discussed and their neuroradiological features are demonstrated.
中枢神经系统（CNS）肿瘤是儿童期最常见的实体瘤，在儿童年龄组中是仅次于白血病的第二大常见恶性肿瘤。幕上肿瘤在2岁以下儿童和青少年中更为常见，而在2至12岁的患者中，起源于后颅窝的脑肿瘤占主导地位。这意味着肿瘤类型、其位置与患者年龄之间存在关联，在鉴别诊断中必须予以考虑。髓母细胞瘤是儿童期最常见的恶性脑肿瘤。在后颅窝，髓母细胞瘤的发病率与星形细胞瘤大致相同。幕上星形细胞瘤是迄今为止主要的肿瘤类型。在本报告中，讨论了一些儿童典型的中枢神经系统肿瘤，并展示了它们的神经放射学特征。
