Giant MCA Aneurysm: A Pediatric Case Report

Abstract

Pediatric cerebral aneurysms comprise anywhere from 0.5-5% of the prevalence of aneurysms in the general population. Giant aneurysms, defined by an aneursysmal size of over 2.5cm, are even less prevalent. Presentation of these aneurysms can vary from increased intracranial pressure, cranial nerve impairment, nausea and vomiting, or mass effect. In this article, we present a patient with a unique constellation of symptoms that presented to the emergency department with a pediatric giant aneurysm and non-specific mass effect symptoms that had a broad etiology and multiple prior workups based on geographical location and other factors that masked the true etiology.
