[Cerebellar liponeurocytoma. Case report].

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. Complete surgical removal with postoperative radiation therapy is recommended. It has a relatively more favourable prognosis. 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.
