title: Cerebellar liponeurocytoma: a case report and review of the literature.
abstract: Cerebellar liponeurocytoma has recently been recognised by the 2000 World Health Organisation classification of tumours of the central nervous system as a distinct clinicopathologic entity. To our knowledge, 18 cases have been reported so far, under different names, such as "lipomatous medulloblastoma, lipidized medulloblastoma, neurolipocytoma, medullocytoma and lipomatous glioneurocytoma". The new classification included cerebellar liponeurocytoma in the category of glioneuronal tumours grade I or II because of its favourable clinical behaviour. The origin and nature of the lipomatous component have been matter of debate and make this tumour entity puzzling. We describe a new case of liponeurocytoma removed from the left cerebellar hemisphere of a 38-year-old-woman. The patient showed unspecific signs of intracranial hypertension and symptoms suggesting a posterior fossa lesion.
