Résumé

One of the most invasive malignant tumors of the cerebellum is medulloblastoma, which is also the most common malignant tumor of the brain in children. Patients with a recurrent disease following initial treatment have the most unfavorable prognosis. The most common metastasis locations are the spine, the posterior fossa, the bones, and the supratentorium. Late medulloblastoma metastasis in the supratentorial intraventricular region is uncommon. We report here a case with supratentorial seeding.

Résumé

Today, stern cell transplantation is a hot topic in scientific circles as a novel therapeutic approach to repair the structure and function of central nervous system. The safe and neuroprotective effects of cell therapy in models and traumatic brain injury patients were evaluated in many experimental and clinical studies in recent decade and somewhat promising results were provided to the scientific community


Nevertheless, there are still obstacles in translating experimental studies in the laboratory into clinical practice that should not be overlooked. In this review study, a brief explanation is provided about biological events and endogenic neurogenesis and angiogenesis after TBI; the performance of transplanted cells in restoration of damaged neurons; the role and potential use of mesenchymal stem cells as adult stem cells preferred in cell transplantation and clinical trials ever conducted in this area; features of cell transplant candidates who will most benefit from transplantation, the type of and proper time for cell transplantation, optimal method for conducting transplant to deliver cells to the brain, and the best dose for effectiveness of transplantation. Finally, the various neuroimaging techniques are discussed, which are used to track and evaluate the survival and implantation of transplanted cells
