Its growth has been always described as locally invasive. This tumor rarely penetrates dura mater and invades extracranial structures. We present a case of GBM, which occurred in a 39-year-old man, with final involvement of the nasal cavity. The patient was operated four times in three years, and a personalized adjuvant chemotherapy regimen was administered in a neo-adjuvant fashion. Histopathological features of the tumor are described. To our knowledge, there are only 9 cases reported in the literature showing this growth pattern and the last case was reported in 1998.
