Pre-operative Magnetic resonance imaging (MRI) of the brain demonstrated a heterogeneous solid extra-axial lesion, in the right cerebellopontine angle with hydrocephalus. The operation was performed via a right retro sigmoid approach. The final histopathological diagnosis was confirmed as liponeurocytoma. Radiation therapy was not done and close observation was maintained during the follow-up for the subsequent 2 years; no signs of recurrence were found.
