Cerebellar liponeurocytoma--a case report

Area of Science:

• Neuropathology
• Neuro-oncology
• Central Nervous System Tumors

Background:

• Cerebellar liponeurocytomas are rare tumors classified under glioneuronal tumors in the 2000 CNS tumor classification.
• These tumors are characterized by two distinct cell populations: neurocytes and lipidized cells resembling mature fat cells.

Observation:

• The tumor typically occurs in adult patients.
• Less than fifteen cases have been documented globally in medical literature.
• This study presents a case in a 32-year-old female patient.

Findings:

• Histopathological examination reveals a biphasic tumor composed of neurocytic and lipidized cell components.
• The tumor exhibits characteristics consistent with cerebellar liponeurocytoma.

Implications:

• Reporting rare tumor cases contributes to a better understanding of their incidence and characteristics.
• This case adds to the limited world literature on cerebellar liponeurocytomas.
• Further research may elucidate the specific origins and behavior of this rare entity.
