RESUMEN
The cerebellar liponeurocytoma is a rarely and recently described tumour. It may be distinguished on the basis of neuroimaging findings that demonstrate the areas of fat density.

We report the case of a 38-year-old woman without particular pathological antecedent with a few months history of headache and dizziness, aggravated since 2 days by signs of increased intracranial pressure and cerebellar dysfunction. The Computerized Tomography practiced in emergency showed a subtentorial space occupying mass, heterogeneous, exhibiting the attenuation values of fatty tissue, with hydrocephalus upstream. The patient has been operated. The histopathological and immunohistochemical studies concluded to a cerebellar liponeurocytoma
