Magnetic Resonance Imaging and Diffusion Weighted Imaging Appearance of Cerebellar Liponeurocytoma

Cerebellar liponeurocytoma is a rare benign neuroepithelial tumor. We describe the case of a 50- year-old man, presenting with signs of increased intracranial pressure and cerebellar dysfunction. Magnetic Resonance Imaging (MRI) showed a heterogeneous, well-circumscribed cerebellar mass with a predominant adipose content. Diffusion Weighted Imaging (DWI) showed an isointense mass with a hyperintense rim Craniotomy demonstrated a soft, gray mass with intratumoral bright patchy yellow areas. Histological and immunohistochemical findings indicated an advanced neuronal, glial and focal lipomatous differentiation with a low level of mitotic activity.
