The imaging findings of pilocytic astrocytomas are classically described as a cyst with an enhancing mural nodule. We report 2 unusual cases of multicystic cerebellar midline masses that were proven to be pilocytic astrocytomas. The uniqueness of the imaging features in these cases may represent an important variant of pilocytic astrocytomas. Recognition of this variant may prevent an unnecessary workup to exclude other etiologies such as parasitic infection (ie, cysticercosis) or cystic metastatic disease.
毛细胞型星形细胞瘤的影像学表现通常被描述为带有强化壁结节的囊肿。我们报告了2例不寻常的多囊性小脑中线肿块病例，经证实为毛细胞型星形细胞瘤。这些病例中影像学特征的独特性可能代表了毛细胞型星形细胞瘤的一种重要变体。认识到这种变体可能避免为排除其他病因（如寄生虫感染，即囊尾蚴病或囊性转移瘤）而进行不必要的检查。
