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.
小脑脂肪神经细胞瘤是一种罕见且近期才被描述的肿瘤。它可根据显示脂肪密度区域的神经影像学表现来鉴别。建议进行完整的手术切除并术后放疗。其预后相对较好。我们报告一例38岁女性病例，该患者无特殊病理既往史，有几个月的头痛和头晕病史，近2天因颅内压升高和小脑功能障碍症状而加重。急诊行计算机断层扫描显示幕下占位性肿块，不均匀，呈现脂肪组织的衰减值，上游有脑积水。患者接受了手术。组织病理学和免疫组化研究结果为小脑脂肪神经细胞瘤。
