Cordoid Meningioma A Case Report

Abstract

Introduction: Meningiomas are tumors of the central nervous system derived from the arachnoid layer of cells, represent less than 3% of all primary intracranial tumors in children, are prevalent in adolescents, and are rare in younger ages. Pediatric cases represent approximately 1.5% of all intracranial meningiomas, and very few cases show aggressive histology. The WHO classification meningioma divided into three grades: Grade I benign; II, atypical; and III, anaplastic / malignant. Chordoid meningioma grade II / atypical meningioma is a rare subtype, which represents only 0.5% of all meningiomas, have high growth rates, higher recurrence and greater possibilities to invade the brain parenchyma compared with meningiomas benign. One possible explanation for the high recurrence rate may be related to the quality mucoid stroma, which facilitates extension of tumor and makes it difficult to achieve a complete resection, which leads to subsequent recurrence.

Case Report: We report the case of male patient 4 years of age diagnosed with meningioma Grade II, with clinic 2 months of evolution who presented progressive neurological deterioration, tumoral exeresis was performed in 3 opportunities and placement system ventriculo peritoneal in the course of 1 month and radiotherapy.

Comments: Accurate diagnosis, therefore, assumes importance because these tumors have an aggressive clinical course and high probability of recurrence so knowing the pathological Clinical Aspects of this rare neoplasm is essential for the Treatment and Comprehensive monitoring.
