[Rare clinical form of glioblastoma multiforme].

Glioblastoma multiforme (glioblastoma multiforme - GBM) is the most malignant tumor classified by WHO. It is also the most common primary CNS tumor with a very aggressive course and unfavourable prognosis, usually develops in adults, and is typically located supratentorially in the fronto-temporal region. However, the literature describes an unusual position of GBM (e.g. spinal cord, pons, pineal region), familial gliomas unconnected with the family of gliomas predisposed to the occurrence of syndromes, unusual glioma and metastatic sites, gliomas transplanted with organs. In this paper, based on the available literature, the authors discuss an unusual and rare form of glioblastoma multiforme.
