Paraganglioma of the filum terminale mimicking neurinoma: Case report

چکیده
BACKGROUND Paraganglioma of the filum terminale is an uncommon tumor of cauda equina region. Lumbar radiculopathies are revelations that can get complicated from cauda equina syndrome. Magnetic resonance imaging (MRI) allows the diagnosis without distinguishing it from a neurofibroma. Only histopathological study can bring certainty in the diagnosis. The treatment of choice is a complete removal. CASE DESCRIPTION We report a case of paraganglioma of the filum terminale in a 74-year-old female patient, admitted for cauda equina syndrome, which has been progressing for 2 years. MRI of medulla objectified an extramedullary lesion at L3-L4, diagnosed as neurinoma. A complete resection of the tumor was performed with a section of the filum terminale, which she was taking since birth. Histology confirmed the diagnosis of paraganglioma. The clinical course was characterized by a complete recovery of the deficit. CONCLUSION Through this case report, the authors discuss clinical and radiological aspects of this tumor, as well as the management in the light of published data.

Paragangliomas are extra-adrenal counterparts of pheochromocytomas and are found at various anatomical sites such as the retroperitoneum, mediastinum, jugular foramen and carotid bifurcation, the latter two fonns being coined as chemodectomas. The vertebral column, especially the llUllbar zone, is one of the rarest sites to be involved by paragangliomas. These lesions may have secretory fun...

Paragangliomas are neuroendocrine tumors that arise from neural crest cells of the sympathetic or parasympathetic autonomic nervous system, most frequently found in the Glomus jugulare and the carotid bodies.

متن کاملGiant Cell Ependymoma of The Filum Terminale: A Case Report
Ependymomas accounts for about 2%–6% of CNS and 60%–70% of spinal cord tumors. Several histological patterns of these neoplasms are well known, but little attention has been devoted to a variant composed of giant cells. In spite of apparently “worrisome” histology, giant cell ependymoma seems to be a neoplasm with a relatively good prognosis. This report presents a case of giant cell ependym...
