Abstract:   (1272 Views)
Background and Importance: Liponeurocytoma is a rare tumor of the CNS. Some of its prominent features include low neuronal proliferation with foci of lipomatous differentiation. So far, 70 reports on cases of brain liponeurocytoma have been published. Most of them were located in the cerebellar hemisphere, but only 7 cases of primary Cerebellopontine Angle (CPA) liponeurocytoma have been reported.
Case Presentation: We presented a 27-year-old woman with a 6-month progressive headache and dizziness. More recently, she developed progressive hearing loss and ataxia. Pre-operative MRI of the brain demonstrated a heterogeneous solid extra-axial lesion in the right CPA with
hydrocephalus. The operation was performed via the retro sigmoid approach. Histopathological diagnosis was confirmed as liponeurocytoma. No radiotherapy was performed. The patient was followed up for two years. There were no signs of recurrence.
Conclusion: Liponeurocytoma is a rare tumor. In most of the cases, it is presented in the cerebellum, and the CPA as the primary location of this tumor is extremely uncommon. Typically, surgery is the treatment of choice for these lesions. If the tumor is subtotal, radiotherapy after operation and
resection can also be advantageous.
