Trieeminal ganglioneuroma

We present the case of an 8-year-old girl with a ganglioneuroma in the left cerebellopontine angle region. The tumor originated from the sensory root of the trigeminal nerve. Histopathologically, it was composed of neoplastic ganglion cells and Schwann cells, leading us to the diagnosis of ganglioneuroma. Intracranial ganglioneuroma is very rare. To our knowledge, this is the first report of a trigeminal ganglioneuroma. The nature and origin of this tumor are discussed and the literature reviewed.
