Imaging-tracked progression of primary leptomeningeal gliomatosis: A case report

This case highlights the importance of careful follow-up and early therapeutic intervention in PLG, as it can be difficult to diagnose leptomeningeal lesions alone. This case also raises the possibility of radiation-induced GBM, and the criteria for diagnosis were fully met. The progression of PLG from the SVZ to the leptomeningeal site was tracked using imaging, providing valuable insights into the pattern of spread of this rare condition.
