Long-Term MRI Observation Following Brain Tumor Resection Reveals Structural Reorganization in the Central Nervous System: Implications for the Extension of ERDP

This study presents a long-term MRI observation of a human case following brain tumor resection, demonstrating progressive structural reorganization within the central nervous system over approximately five years. Serial MRI analysis revealed stepwise reduction of a postoperative parenchymal defect, transition into a linear structure, and eventual integration with surrounding brain tissue, accompanied by sustained functional recovery and absence of recurrence. These findings are interpreted within the framework of the Emergency Regenerative Defense Program (ERDP), a proposed systemic immune–regenerative reorganization mechanism induced by localized mechanical stimulation. The observations suggest that ERDP-mediated reconstruction may extend beyond peripheral tissues to the central nervous system, challenging the conventional assumption of limited regenerative capacity in human brain tissue. This study is presented as a hypothesis-generating single-case report.
