====== Ganglion cell tumor ====== These are neoplasms composed of neoplastic [[neuron]]al cells, a [[gangliocytoma]], or a combination of neoplastic[[ neuron]]s and neoplastic [[glial cell]]s, a [[ganglioglioma]]. At times a low-grade glial neoplasm with trapped, but non-neoplastic neurons, is mistaken for a [[ganglioglioma]].
