How I do it: pediatric lateral-type posterior fossa ependymoma resection

Abstract Background Lateral-type ependymomas, or cerebellopontine ependymomas, of the posterior fossa are rare tumors extending into the cerebellopontine angle, encasing important neurovascular structures, presenting as a particular surgical challenge. Method We performed a radical resection of lateral-type ependymoma in a 2-year-old patient with anamnesis of torticollis and vomiting. Resection of the tumor was preceded by insertion of external ventricular drainage. Conclusion Optimal treatment improving prognosis requires achieving gross total resection of the tumor.
