They have some common neuroradiological and histological features with malignant brain tumors (malignant glioma of infancy, PNET), but another prognosis. Aggressive clinical course, rapid tumor growth, MR-based differential diagnosis involving multiple histological forms and histopathological findings potentially mimicking malignant tumor complicate differential diagnosis, as it was in the second case. Probably, such an aggressive clinical course is associated with significant spread of neoplastic astrocytic and neuronal components with foci of primitive embryonic cell complexes with increased proliferative index. Surgery is preferable. Difficult resection of these tumors is associated with rich vascularity, high risk of fatal bleeding, no border with normal brain tissue, and tendency to infiltrate functionally significant structures of the central nervous system.</p>","PeriodicalId":24032,"journal":{"name":"Zhurnal voprosy neirokhirurgii imeni N.
