Abstract

In 1982, Hassoun et al. reported two cases of differentiated neuroblastoma with the clinical and light microscopic appearance of intraventricular oligodendroglioma and gave a name of "central neurocytoma" to this tumor. Jerdan et al. (1983) called the similar tumor as "differentiated cerebral neuroblastoma in adults". As the tumor can be diagnosed only by ultrastructural study, the established cases so far reported are very rare. In this paper we present five cases identical to those presented by Hassoun et al. and clarify the essential nature of this new category of brain tumors. All of our cases of central neurocytoma occurred in the lateral ventricles of young adults. Clinically there was no evidence of leptomeningeal or ventricular dissemination of tumor cells. After subtotal resection of the tumor and 6000 rads of whole brain irradiation, the tumor mass disappeared and no evidence for recurrence of the tumor was noted on CT scan. All cases showed almost the same histology. The tumor cells contained a small round and/or oval nucleus, and had eosinophilic thin delicate cytoplasmic processes. There were no Homer Wright rosette, but were anuclear spaces consisting of fine fibrillar structures, like so called "broad rosettes" o...Continue Reading
