    Background: Rosette-forming glioneuronal tumor (World Health Organization grade I) is considered as a benign tumor with very low potential for progression. The potential for malignant transformation of this tumor is not known and has never been reported before in literature.

    Case Description: We report a 42-year-old man, diagnosed with rosette-forming glioneuronal tumor of the fourth ventricle with a positive isocitrate dehydrogenase 1 mutation, progressed to glioblastoma after 6 years from diagnosis. We discuss the clinical history, radiological findings, and histopathological characteristic with immunohistochemistry findings observed in this unique case.

    Conclusions: Despite being acceptable as benign, based on our observations in this case, there is a potential for malignant transformation of rosette-forming glioneuronal tumor. The role of isocitrate dehydrogenase 1 mutation leading to malignant transformation could not be established as our finding is novel and further prospective studies are required to prove this association.

    Dandy-Walker syndrome is a rare congenital malformation of the brain that involves the cerebellum and the fourth ventricle. It is characterised by a classical triad of hydrocephalus, cystic dilatation of the fourth ventricle and complete or partial agenesis of the vermis. Majority of cases are diagnosed during neonatal or early infantile period. In this case report, a seven-year-old boy complained of recurrent headaches for the past one year. Physical examination was unremarkable. Examination of the fundus on the same day revealed bilateral papilloedema. His subsequent computed tomography scan of the brain done at a major district hospital demonstrated features in keeping with Dandy-Walker malformation. Our case highlighted the importance of embarking on a detailed and thorough approach when dealing with a child with chronic headache, especially in rural settings where advanced medical equipment is not readily available.
