European Low Grade Glioma Network 2026
ELGGN 2026
Welcome to the 20th Anniversary Meeting of the European Low-Grade Glioma Network (ELGGN)
Dear colleagues and friends of the European Low-Grade Glioma Network (ELGGN).
The 20th edition of the ELGGN annual meeting will take place in Montpellier, on April 23-25, 2026.
For two decades, the ELGGN has united neurosurgeons, neuroscientists, neuro-oncologists, neuroradiologists, and rehabilitation specialists around a common goal: to understand and preserve the human brain while improving the lives of patients living with diffuse low-grade gliomas.
Founded on a spirit of collaboration, open dialogue, and translational research, the ELGGN has grown into a dynamic community that bridges clinical expertise and neuroscience innovation across Europe and beyond. Together, its members have shaped the modern concepts of functional neuro-oncology — redefining how we map, operate, and monitor brain plasticity in glioma patients.
The 20th Anniversary Congress in Montpellier will celebrate this collective journey and look ahead to the future of low-grade glioma care.
Join us where it all began — at the crossroads of science, surgery, and human resilience — as we honor twenty years of progress and envision the next era of functional, multidisciplinary, and personalized neuro-oncology.

Venue: The Botanical Institute, University of Montpellier
Nestled in the historic heart of Montpellier, the Botanical institute of the University of Montpellier offers a unique setting where science, history, and culture converge. Founded in the 16th century alongside the world-renowned Faculty of Medicine—the oldest continuously active medical school in the Western world—the Institute stands adjacent to the Jardin des Plantes, France’s oldest botanical garden, created in 1593 by Henri IV. Located just a few steps from the historic Faculty of Medicine and the Saint-Pierre Cathedral, the Institute of Botany will provide an inspiring backdrop for the 20th Anniversary Meeting of the European Low-Grade Glioma Network, where tradition meets innovation in the pursuit of scientific progress.
Location:
163 rue Auguste Broussonnet, 34090 Montpellier
