Primary cerebral ganglioneurocytoma in an adult.

Abstract

A case of an unusual cerebral neuronal tumor in a 37-year-old woman is described. A clearly marginated tumor, which was found to occupy the septum pellucidum, genu of the corpus callosum, and right frontal lobe, was composed of ganglionic and small round cells. These two populations of neoplastic cells were both interpreted as being in the advanced stages of neuronal maturation, and the authors thus designated this tumor as a "ganglioneurocytoma." Related nosologic problems on central neuronal tumors and their possible histogenesis are also discussed.
