Chiaramonte et al. report the clinical, radiological and pathological characteristics of a cerebellopontine angle liponeurocytoma in a 35-year-old woman. A review of the literature is also provided. This unusual cisternal location raises the issue of the differential imaging diagnosis with much more common cerebellopontine angle tumors (meningiomas, vestibular schwannomas, ependymomas, epidermoid cyst, hemangioblastomas and medulloblastomas).

To the best knowledge 59 cases of cerebellar liponeurocytomas have been reported, including only 6 cases of cerebellopontine angle liponeurocytomas. The treatment relies on total removal whenever possible with an excellent prognosis, but a high MIB-1 index (>10%) and/or incomplete tumor resection are the main adverse prognostic factors ¹⁾.
