Abstract
Over the course of five years, a total of ten cases were collected of glioma patients in whom a distant lesion at the fourth ventricle was noted. A 'distant lesion' was defined as a lesion with a normal appearing tissue bridge at imaging between the primary and secondary locations. Previous imaging of these patients was reviewed along with clinical history, course of therapy, and available histology. A review of the literature was performed with respect to present knowledge on patterns of glioma proliferation and dissemination. This case series is the first to describe the fourth ventricle as a location that may be prone to secondary lesions in glioma patients. Further investigation on this subject may yield deeper insights into the mechanisms by which glial tumors spread within the brain, with the hope of developing or improving therapeutic targets.
