摘要

毛细胞星形细胞瘤(PAs)是儿童最常见的原发性脑肿瘤。它们是世界卫生组织一级肿瘤，预后良好。在儿童中，小脑、视神经交叉和下丘脑区域是最常见的位置。临床上，脑神经麻痹、颅内压升高和共济失调是常见的症状。我们提出一个不寻常的情况下，PA在一个3岁的幼儿不能走路。后窝肿瘤的诊断需要高度的怀疑指数，因为它们可以迅速恶化。

Cerebellar pilocytic astrocytoma: Unusual presentation in a 3-year-old girl with classical imaging features

Pilocytic astrocytomas (PAs) are the most common pediatric primary brain tumor. They are World Health Organization Grade 1 tumors with an excellent prognosis. In children, the cerebellum, optic nerve chiasm, and hypothalamic region are the most common locations in that order. Clinically, cranial nerve palsies, symptoms of raised intracranial pressure, and ataxia are commonly seen. We present an unusual case of PA in a 3-year-old toddler with inability to walk. High index of suspicion is required for the diagnosis of posterior fossa tumors in this age group as they can deteriorate rapidly.
