  1. Metastasis
  2. Pilocytic astrocytoma

Congratulations to those who selected hemangioblastoma. The enhancing mural nodule and non-enhancing cyst wall are characteristic features. Cyst walls of pilocytic astrocytoma often enhance, and it usually occurs at a younger age. Metastasis has rim enhancement.
