A massive ganglion cell tumor with unusual localization and favorable outcome

Abstract

Gangliocytomas are neoplasms of the central nervous system which are deriving from mature neuron cells. In the following case, we present the clinical, neuroimaging, and histopathological findings of a massive ganglion cell tumor involving the left cerebellar hemisphere with extension throughout the whole brainstem, including midbrain, pons, and medulla oblongata.
