One half of brain tumors in children originate in the posterior fossa. Although a wide variety of lesions occurs, four tumor types account for more than 95% of cases. Knowledge of their modes of presentation, CT and MR features, and pattern of spread can usually lead to a correct diagnosis.
儿童脑肿瘤中有一半起源于后颅窝。虽然会出现各种各样的病变，但四种肿瘤类型占病例的95%以上。了解它们的临床表现方式、CT和MR特征以及扩散模式通常能得出正确的诊断。
