Ependymoma is the third most common brain tumor in children. Extracranial metastases of ependymomas are uncommon. A 21-month-old Japanese boy was diagnosed to be brain dead due to a posterior fossa (PF) brain tumor. Surgical resection of the tumor was not performed. Twenty-seven months later, he developed a truncal subcutaneous tumor, which was pathologically diagnosed as PF ependymoma group A. We observed the intracranial recurrence of the brain tumor, an invasion to the left orbit, and a neoplasm in his liver before he died. This case suggests that PF ependymoma group A can metastasize extracranially to various organs.
