Abstract
Cerebellar liponeurocytoma consists of well-differentiated neurons with the cytology
of neurocytes in addition to a population of lipidized cells. Hence it is biphasic
in appearance and has been included in the category of glioneuronal tumors of the
central nervous system by the WHO working group on the Classification of Tumors of
the Nervous System. However, liponeurocytoma is not exclusive to the cerebellar or
fourth ventricular location. Since its inclusion in the central nervous system tumor
classification, nine cases with similar histological and immunohistochemical features
have also been described in the lateral ventricles. We describe here such a lateral
ventricular tumour in a 30-year-old woman, characteristically showing divergent glio-neuronal
differentiation and lipidized neoplastic cells. Therefore, we suggest that future
WHO tumor classification should consider that liponeurocytomas are not entirely restricted
to the cerebellum and henceforth change of nomenclature might be considered, as also
pointed out by other authors.
