Novel case of recurrent intraventricular atypical central neurocytoma with prominent gangliogliomatous differentiation in a 10-year-old boy with 10 years of follow up.

Central neurocytoma is a rare neuronal tumor that typically occurs in young adults. Infrequently, these tumors exhibit advanced neuronal maturation and glial differentiation, giving rise to a histologically diverse tumor, in contrast to a typical central neurocytoma. We present a novel case of intraventricular central neurocytoma with prominent gangliogliomatous differentiation that developed atypical features upon recurrence after 10 years of follow up in a 10-year-old boy. Our case provides insight into the divergent differentiation capability of a neurocytic tumor and illustrates the diverse histological features of this rare entity.
