[Clinical course of supratentorial brain tumors in children and adolescents].

The classical concept concerning the character of development of the blastomatose process in the brain is frequently altered when applied to children and adolescents with supratentorial newgrowths. An analysis of 102 cases with verified newgrowths of a different histological nature and localization in the supratentorial space permitted to distinquish 4 types of a clinical development of this kind of pathology: (1) with an acute onset and short-term development of the tumor process; 2) with a gradual, progressive increase of symptoms, but with expressed and long-term remissions; 3) with a slowly progressive development of the disease and a sudden severe syndrome of decompensation or terminal state; 4) with acute clinical signs of a newgrowth and a replacement by a subsequent progressive remittent development.
