ABSTRACT

The treatment of central nervous system tumors is still a major challenge for the oncological and neurosurgical teams. Due to the heterogeneous histological and topological characteristics of these neoplasms, every case requires individual evaluation. In addition to histology and stage, survival is largely determined by the extent of resection, which can be severely limited by the proximity of eloquent brain regions. A key component of current modern neuro-oncological care is the planning and execution of surgical intervention to ensure the longest possible progression-free survival with adequate quality of life. The simultaneous development of several pre- and intra-operative imaging modalities is making optimal therapy more and more accessible and safe. Structural, diffusion and functional MRI offers the possibility to visualize the tumor and the surrounding areas both before and during surgery. For the surgeon, the optimal intra-operative environment, orientation and visual acuity are provided by increasingly sophisticated microscopes, navigation devices, intra-operative imaging equipment, endo- and exoscopes.
