Extraventricular neurocytoma in a child mimicking oligodendroglioma: a diagnostic pitfall

Extraventricular neurocytomas are rare neuronal tumours that have been included in the 2007 WHO classification as a variant of central neurocytoma. They arise outside the ventricles, usually within the cerebral hemisphere,s but also in other regions throughout the neuraxis. The morphological overlap...

Summary:Extraventricular neurocytomas are rare neuronal tumours that have been included in the 2007 WHO classification as a variant of central neurocytoma. They arise outside the ventricles, usually within the cerebral hemisphere,s but also in other regions throughout the neuraxis. The morphological overlap of these tumours with oligodendroglioma often poses diagnostic difficulty. Herein, a case of extraventricular neurocytoma in a 4-year-old girl is reported that mimicked histologically oligodendroglioma. The authors describe the clinicopathological features of this rare entity with special emphasis on differential diagnosis.
