Gliomatosis cerebri is a primary central nervous system (CNS) tumor. This means it begins in the brain or spinal cord. This tumor is no longer recognized as a formal diagnosis, rather gliomatosis cerebri refers to a special pattern of diffuse and extensive growth of glioma cells, invading multiple lobes of the brain. Gliomas of different grade and cell of origin (astrocytes, oligodendrocytes) can grow with this pattern, and very little is understood about the molecular basis of the disease. More research is needed to discover the origin of these tumors and to improve their treatment.

Spatial Evolution and Somatic Mutations Spectrum of Gliomatosis Cerebri
The development of treatment for Gliomatosis cerebri and other high grade gliomas relies on a comprehensive understanding of each tumor type. Using the Pediatric Brain Tumor Atlas alongside other open access datasets, researchers will map and analyze how tumors change over time, across locations, and the specific proteins created in Gliomatosis cerebri.
