Tonic-Clonic Seizure
  • A 51-year-old right-handed woman initially presented with generalized tonic-clonic seizures. MRI showed abnormal signal hyperintensity of the right temporal lobe that was thought to be consistent with ischemic stroke.[ncbi.nlm.nih.gov]

  • The etiology of gliosarcoma remains speculative although it is recognized that gliomas can induce sarcomatous transformation in the supporting mesenchymal elements (2) and irradiation of the central nervous system can induce malignant transformation of[path.upmc.edu]
  • Etiology: It is thought that the sarcomatous changes may arise from fibroblasts of the blood vessels. Gross: The glioblastoma part of the tumor forms heterogeneous infiltrative areas with hemorrhage and necrosis.[aboutcancer.com]


  • Although most gliomas rarely show metastases outside the cerebrum, gliosarcomas have a propensity to do so, most commonly spreading through the blood to the lungs, and also liver and lymph nodes.Gliosarcomas have an epidemiology similar to that of glioblastomas[en.wikipedia.org]
  • Due to its rarity, the pathogenesis, epidemiology and optimal therapy of GS have been based on small retrospective cohort studies, with treatment presently utilizing regimens established for other high-grade gliomas, including combination of resection[ncbi.nlm.nih.gov]
  • They share similarities with glioblastomas as far as clinico-epidemiological and prognostic factors are concerned. They are commonly cortically-surfacing lesions occurring mostly in the supratentorial compartment.[ncbi.nlm.nih.gov]
Sex distribution
Age distribution


  • Because of the natural barrier of the dura mater, that prevents intra or extradural neoplasm dissemination, cases of penetration of the dura and cranium by gliosarcomas without previous surgery or radiation are very rarely reported.[ncbi.nlm.nih.gov]
  • Awareness of the phenomenon of melanocytic differentiation within primary neuroepithelial and glial neoplasms is important to prevent the misdiagnosis of these tumors such as metastatic melanoma or primary melanocytic neoplasms of the CNS.[ncbi.nlm.nih.gov]
