A cerebellar neurocytoma with an excellent response to radiotherapy: a case report
Abstract Background: Extraventricular neurocytoma (EVN) is a rare central neurocytoma with neoplasms occurring in the brain parenchyma outside the ventricular system with similar biological behaviours and histopathological characteristics. Cases of EVN reported in the brainstem and cerebellum are fairly rare. In addition, very few cases with radiotherapy as the only treatment have been reported, and their outcomes were unclear.Case presentation: We reported an EVN of the brainstem and cerebellum confirmed by pathology in a 43-year-old male presenting with unprovoked nausea and dizziness. The patient showed a favourable outcome with only radiotherapy during the 2-year follow-up.Conclusions: Patients who have EVN may have a favourable prognosis with radiotherapy without surgery.
