Liponeurocytoma of Cerebellum

Abstract

Cerebellar liponeurocytoma (LNC) is a very rare neuroepithelial tumor. About thirty eight cases have been reported, in literature till date, mostly in the form of isolated case reports due to rarity of the occurrence. Authors report interesting case in 27-year old male presented with headache and cerebellar signs. MRI imaging revealed posterior fossa mass. He underwent sub occipital ctraniectomy with gross total resection of lesion. Histopathological report of specimen was consistent with liponeurocytoma with range of MIb index less than three. He is under regular follow-up. However he was not advised any adjuvant therapy. Diagnosis of LNC requires high index of suspicion and neuroimaging with typical MRI findings may be help to confirm the diagnosis. The tumor needs to be differentiated from medulloblastoma, which is far more common and aggressive and requires post-operative chemo-radiation and carries poor prognosis Management and pertinent literature will be reviewed.
