Pilocytic astrocytoma (PA) commonly occurs during the first two decades of life. Typical locations include cerebellum, optic nerve, optic chiasm/hypothalamus and brainstem. PA should be considered in the differential diagnosis of patients with brain tumors manifesting with hemorrhagic onset. We report a case of a hemorrhagic onset of cerebellar PA in a young adult with imaging findings mimicking cavernous angioma. We also discuss imaging features and histological characteristics with a focus on the etiology of the hemorrhagic onset.
毛细胞型星形细胞瘤（PA）常见于生命的前二十年。典型部位包括小脑、视神经、视交叉/下丘脑和脑干。对于以出血起病的脑肿瘤患者，鉴别诊断时应考虑PA。我们报告一例年轻成人小脑PA出血起病的病例，其影像学表现酷似海绵状血管瘤。我们还将讨论其影像学特征和组织学特点，重点关注出血起病的病因。
