Neurocytoma of the thoracic spinal cord.

Central neurocytoma is an unusual tumour that arises in the supratentorial ventricular system of young adults. Similar lesions, termed simply neurocytoma, have been described at a variety of locations outside the ventricular system. Here, we report the case of a 50-year-old man who presented with pain and a rapidly progressive myelopathy due to a neurocytoma of the upper thoracic spinal cord. The literature on spinal neurocytoma and its relation to central neurocytoma are discussed.
