Caracterización de los pacientes con ependimoma intracraneal en el hospital pediátrico Juan Manuel Márquez. 2012-2017

Introduction: ependymoma are almost 3-5 % of the intracranial tumors and 5-10 % of the brain tumors in pediatric age. Objective: to characterize the patients with intracranial ependymoma who underwent surgery in the Pediatric Hospital ¨Juan Manuel Marquez.¨ Materials and methods: retrospective, descriptive study of patients in pediatric age with histological diagnosis of ependymoma of intracranial location in the period January 2012-December 2017. The universe was formed by all patients of pediatric age who underwent surgery with histological diagnosis of intracranial ependymoma in the before-mentioned place and period (N=22). Results: the average age was 2.75 years with limits between 1 and 17 years old. Male patients represented 63.64 %; the relation with female sex during the first 4 years was 1:1.  Regarding the clinical characteristics, hydrocephaly predominated in 72.73 % of patients. Intracranial ependymoma of infratentorial location (63.64 %) predominated. 45.45 % of the studied lesions corresponded to the histological subtype of anaplastic ependymoma. Conclusions: the combination of surgery, radiotherapy and chemotherapy was used in most of the cases. The direct approach of the lesion through craniotomy and a removal adequate to ependymoma location predominated. However, in most of them just the resection of 50-90 % was achieved. The evolution of most of patients after the diagnosis evidenced a tendency to the stability.
