PARAGANGLIOMA OF LUMBAR SPINE – A RARE CASE REPORT

Paragangliomas are neuroendocrine neoplasm. These neoplasms originate from specialized neural crest cells and have association with segmental or collateral autonomic ganglia. Spinal paraganglioma is rare tumor. We are presenting a case of spinal paraganglioma in a 58 years old male presented with low back pain, his MRI spine showed extramedullary intradural tumor at the level of L1-L2 vertebra .Tumor was excised and patient was discharged after uneventful stay at hospital. Paragangliomas are WHO grade I slow growing tumor, radiologically paraganglioma resembles other lesions, such as schwannomas, ependymomas, meningiomas. Gross total resection of tumor is treatment of choice .Prognosis is good with very rare recurrence rate.

Percutaneous embolization of sporadic lumbar nerve root haemangioblastoma under local anaesthesia

Pre-operative embolization of spinal tumours are mainly performed using a transarterial approach. Percutaneous embolization of spinal tumours are undertaken much less frequently, though its use has been reported in hypervascular spinal metastases 1,2 and spinal paraganglioma. 3 We present a patient in whom pre-operative percutaneous embolization has been performed to a recurrent lumbar nerve root haemangioblastoma that had previously been embolized using a transarterial approach. Percutaneous embolization, through targeted percutaneous puncture of the extradural component, helped reduce intraoperative blood loss, and minimize risk of spinal ischaemia.

Extradural Dorsal Spinal Paraganglioma: A Rare Case Report and Literature Review

Paragangliomas are neuroendocrine tumors originating from specialized cells of neural crest derivative. They are mostly found in the carotid and jugulotympanic region. Paragangliomas are extremely rare in the spine, and in literature, most cases are described as intradural extramedullary lesion in the cauda equine or filum terminale region. Extradural dorsal spine paragangliomas are even rarer, and till date, only 11 cases are reported in available literature. We describe a case of an adult woman who presented with mid dorsal region pain and sensory-motor spastic paraplegia. Imaging features were suggestive of D5 Pott's spine with epidural granulation tissue. Perioperatively, the tumor was moderately vascular and complete excision done. On HPE and IHC, diagnosis of paraganglioma was made. There was no evidence of clinical recurrence of the lesion at 6 months follow-up.
