Abstract
A rare, slow growing biphenotypic tumor arising in the region of the fourth ventricle. It shows a benign histology and favorable postoperative course corresponding to WHO 2007 grade I. Rosette-forming glioneuronal tumor (RGNT) of the fourth ventricle affects young adults most commonly. Population-based incidence rates are not yet available. RGNT was first recognized and characterized as a distinct disease in a report of 11 cases by Komori et al. in 2002 and recently added as a new entity in the 2007 WHO classification of tumors of the central nervous system.
