Ependyma-lined cysts.
Ependyma-lined cystic lesions of the subarachnoid space are uncommon. They form a histologically heterogeneous group and have been referred to as epithelial, ependymal, glioependymal and neuroepithelial cysts depending on their respective histological characteristics. In this report, we describe two cases of ependyma-lined cysts in the posterior fossa that support a common pathogenesis for this diverse group of lesions.
