Posterior dural arteriovenous malformation and medulloblastoma in an infant: case report.

A newborn is described who presented with heart failure from a posterior dural arteriovenous malformation and had a coexisting congenital medulloblastoma. There have been sporadic reports of arteriovenous malformation and brain neoplasms in older children and adults, and these have generally been glial tumors. This is the first known case of a combined congenital primitive neuroectodermal tumor and arteriovenous malformation in an infant.
