Two primary brain tumors in one child.
We studied a 4-year-old boy with symptoms and signs of a posterior fossa tumor. CT showed two separate intracranial tumors: a fourth ventricle choroid plexus papilloma and a frontal subependymal giant-cell astrocytoma. This case emphasizes that, even in the absence of special genetic predisposition to CNS tumors, two separate intracranial masses may not represent CSF metastasis of a single primary tumor.
