Perianal Ependymoma Presenting in the Neonatal Period

Abstract

Extraspinal ependymomas are a rare type of glioma that may arise in the sacrococcygeal region, presenting as a pelvic mass in an infant or child. Ependymoma presenting in the newborn period has not been described previously. Herein we describe a case of a newborn boy who presented with a perianal ependymoma, which was subsequently found to have presacral extension. The major diagnostic challenge this case presented was to rule out the alternative diagnosis of sacrococcygeal teratoma or a developmental malformation/heterotopia.
