Recurrence of supratentorial ependymoma in a brazilian child

Abstract

Ependymomas are tumors resulting from neoplasms in ependymal cells. They represent the third most common tumor of the central nervous system in pediatric patients, occurring more frequently intracranially, in addition to having a high rate of local recurrence. Three-dimensional reconstruction is an emerging technology that promises benefits to professionals, patients, and students. We report the case of a 3-year-old female patient with a recurrent left frontal ependymoma, as well as its unique 3D reconstruction. The primary lesion was clinically manifested by gait imbalance, and recurrence was identified by resonance magnetic imaging. This type of tumor requires resection surgery as main treatment, and total removal is associated with lower mortality and low recurrence rate. Despite that, in the present study, the primary lesion was partially resected, which represents a tendency to recurrence. The case was presented through a 3D reconstruction of the recurred intracranial lesion and the postoperative period, based on image exams of the patient, to discuss the surgical approach. In addition, the 3D model is an innovation that allows preoperative practice by neurosurgeons and improves the clinical understanding of the patient and their family by enabling the observation of structures. Also, it aids in medical education by ensuring 3D visualization, essential for the study of anatomy. Therefore, the present work adds to the scientific literature new possibilities offered by 3D reconstruction technology.
