    Abstract:
    Rosette-forming glioneuronal tumor (RGNT) of the fourth ventricle has been recognized as a new type of glioneuronal tumor. RGNTs are typically located in the infratentorial midline with involvement of the fourth ventricle. They occasionally involve the aqueduct and/or vermis. RGNTs of unusual anatomical sites or those with unusual findings have been reported. The present case reports describe RGNT of the fourth ventricle with bilateral olivary degeneration. It is important to accumulate imaging findings and biological behaviors of RGNTs given the limited number of cases.
