title: Rosette-forming glioneuronal tumor of the fourth ventricle.
abstract: We present a case of a 22-year-old asymptomatic female whose CT study (performed following trauma) incidentally discovered a posterior fossa mass. The lesion was further evaluated with a MRI study, and (following discussion with the patient and her family) elective surgical resection of the lesion was performed. On pathology, histological evaluation revealed a diagnosis of rosette-forming glioneuronal tumor of the fourth ventricle. RGNT of the fourth ventricle or posterior fossa should always be considered in the differential diagnosis of infratentorial lesions, especially in young adults.
