چکیده

The MR and pathologic features of a case with neuroendocrine tumor (paraganglioma) of the cauda equina are presented. MR showed the tumor to be hyperintense on postcontrast examination and also showed serpiginous flow voids suggesting vessels capping the tumor. A neuroendocrine tumor should be considered in the differential diagnosis of tumors in this location.

Paraganglioma of the cauda equina with associated intramedullary cyst: MR findings.

The MR imaging features of a paraganglioma of the cauda equina with associated spinal cord cysts are presented. MR imaging showed the tumor to be isointense with the spinal cord on all pulse sequences and to enhance homogeneously. The intramedullary cysts had increased signal intensity on proton density- and T2-weighted images, and involved the cervical and thoracic regions.

Paraganglioma of the cauda equina. A case report and review of the literature.

A 59-year-old man presented with clinical evidence of a primary tumor of the cauda equina region. It was well circumscribed and was completely removed by neurosurgery. Routine staining showed that it had structural similarities to an ependymoma, but immunohistochemistry with antisera to synaptophysin, NSE, chromogranin-A and PGP 9.5 proved it to be a neuroendocrine tumor, i.e. a paraganglioma. ...

Spinal Paraganglioma Adherent to the Cauda Equina

Paragangliomas are rare among intradural spinal tumors. Most of them are benign, but aggressive behavior and local recurrence can occur. Cases of paraganglioma are, difficult to diagnose radiologically; hence, diagnosis is confirmed histopathologically. Radiologically, paragangliomas are similar to ependymomas, and, histopathologically, they are similar to neuroendocrine tumors. We evaluated th...

[Cauda equina syndrome caused by paraganglioma of the filum terminale].

Paragangliomas are neuroendocrine tumors that originate from cells migrating from the neural crest. They have a diverse localizations, and are common in the head, neck, mediastinum or retroperitoneum. Their growth in the filum terminale region is very infrequent. We report the case of a patient who suffered an acute cauda equina syndrome. We give a detailed description of the diagnostic process...

© 2016 Surgical Neurology International | Published by Wolters Kluwer Medknow Abstract Background: Cauda equina paragangliomas (CEPs) are rare spinal tumors that are mostly misdiagnosed preoperatively as ependymomas or schwannomas on magnetic resonance imaging (MRI). Clinically, they usually present with the gradual onset of back pain and radiculopathy rather than an acute cauda equina syndrome...
