Abstract

Background: Although recurrent anaplastic ependymoma in pediatric patients is not uncommon, recurrent disease leading to widespread metastases to the peritoneum is extremely rare. Case Report: We present a case of an 18-month old male who initially presented with posterior fossa anaplastic ependymoma, who then proceeded to present 1 year later with spinal recurrence, and then 2 years after that with widespread disease involving the intracranial ventricular system and peritoneum. Conclusion: We posit that surgical interventions to treat primary and recurrent presentations in combination with a conduit to the peritoneum via a ventriculoperitoneal shunt contributed to the mechanisms of this complex case.
