Cerebral edema associated with Gliadel wafers: Two case studies

Abstract

While the introduction of carmustine wafers (Gliadel wafers) into the tumor resection cavity has been shown to be a beneficial therapy for malignant glioma, it is recognized that clinically significant cerebral edema is a potential adverse effect. Following are two clinical case reports demonstrating profound cerebral edema associated with implantation of Gliadel wafers. As a result, one of these individuals had premature death. A brief literature review is provided to assist in explaining the mechanisms by which clinically significant cerebral edema may develop. Copyright © 2005 by the Society for Neuro-Oncology.
