A rare case of a pediatric extraventricular neurocytoma: case report and review of the literature.

摘要

Central neurocytomas are well-demarcated, intraventricular tumors that display neuronal differentiation. Fifty percent of these lesions are located in the frontal horn or the body of the lateral ventricle near the foramen of Monro [2]. Extra-ventricular central neurocytoma refers to a rare parenchymal tumor with neurocytoma features. These tumors tend to be large, well-circumscribed lesions located in the cerebral hemispheres, most commonly in the frontal and parietal lobes, although they have been found in the thalamus, cerebellum, pineal region, and even in the spinal cord [15]. Although no consistent chromosomal gains or losses have been seen, 1p19q co-deletions have been found. This finding does not seem to imply a more favorable prognosis as with oligodendrogliomas [10, 13].
