“…Neurocytoma is an uncommon tumor; exceptional cases have been reported in spinal cord [1,3,5,[7][8][9][10][11][12]. Spinal Neurocytoma has clinical and pathological similarities to some of these tumors, namely, oligodendroglioma and ependymoma, and probably it has been frequently misdiagnosed in the past.…”

Ganglioneurocytoma of the spinal cord: report of a case and review of literature

et al. 2008

A case of ganglioneurocytoma of the spinal cord in a 51-year-old man is reported. Patient presented with a progressively worsening back pain and hyposthenia of lower limbs. Magnetic resonance imaging of the spinal cord revealed an intradural lesion in the T10-11 spinal segments, hyperintense on T1-weighted sequences. Complete resection was achieved. The patient did not show evidence of recurrence 12 months after surgery. On histology, the lesion was composed of round to oval cells with fine granular, slightly eosinophilic to clear cytoplasm suggesting a neurocytic differentiation. Some ganglion cells were observed. Neither significant cytologic atypia nor mitoses were present. The neoplastic cells were strongly positive with synaptophysin and negative with glial fibrillary acid protein. Neurocytomas are uncommon tumors typically arising within the lateral ventricles near the foramen of Monro. Extraventricular neurocytomas have been reported at various sites with rare examples in spinal cord. In the present paper, a case of ganglioneurocytoma of the spinal cord is reported with review of literature and discussion of differences compared to neurocytomas of other sites.

“…He described a neuronal tumor with pathological features distinct from cerebral neuroblastomas, occurring in lateral and third ventricles, and histologically mimicking oligodendrogliomas. Subsequently, tumors mimicking neurocytomas but occurring within the cerebral hemispheres (cerebral neurocytomas) 14 , or the spinal cord 10,11,[15][16][17] were documented. The term "extraventricular neurocytoma" is now applied to neoplasms that share histological features with the neurocytomas but arise outside the ventricular system 18 .…”

“…They are usually located in the lateral, third and less often, in the fourth ventricles 2 . Case reports have documented the involvement of cerebral hemispheres (commonly frontal followed by parietal) 4 , thalamus 5 , cerebellum 6 , pons 7 , pineal gland 8 , retina 9 , and spinal cord 10,11 .…”

Central neurocytomas are typically located in lateral or third ventricles. Here, we report a case of neurocytoma located in the middle cerebellar peduncle. A 36-year-old male patient presented with symptoms of ataxic gait and urinary incontinence for one month. Magnetic resonance imaging (MRI) of the brain revealed a slightly enhanced lesion on the left middle cerebellar peduncle with obstructive hydrocephalus. The preoperative diagnosis was a glial tumor and a subtotal surgical removal was performed. Following pathological studies, the final definitive diagnosis was made as central neurocytoma. Six months after surgery, the patient presented with low back pain and bilateral lower extremity weakness. Lumbar MRI studies revealed multiple intradural-extramedulary lesions. The patient was not operated for spinal lesions. He was treated with palliative radiotherapy in the metastatic spinal area. Cerebellar peduncle is an atypical location for a neurocytoma. Neurocytomas in atypical locations may behave more aggressively and make spinal seeding. According to neuroradiological and clinical presentation, these tumors may have been confused with other common cerebellar lesions. Pathological examination is needed for definitive diagnosis. Favorable prognosis is related to total tumor excision.

“…Only 15 cases have been reported in the spinal area in the English literature [2][3][4][5][6][7][8][9][10][11][12][13]. Fourteen cases were presented as an intramedullary lesion with spinal cord enlargement and one case originated from the cauda equina area as an extramedullary lesion on MRI studies.…”

Extraventricular neurocytoma (EVN) in the spinal cord is extremely rare and only 15 cases have been reported in the English literature. Fourteen cases presented as an intramedullary lesion with spinal cord enlargement in cervico-thoracic segment and one case presented as an extramedullary lesion originating from cauda equina. Herein, we report an unusual spinal neurocytoma with exophytic growth from the thoracic spinal cord with cord compression mimicking meningioma. To our knowledge, this is the first case of exophytic spinal neurocytoma recorded in the English literature.
