# Intradural Extramedullary Thoracic Spinal Paraganglioma in a Young Adult: A Case Report

## TL;DR

A young adult had a rare spinal tumor removed and recovered well after surgery and radiotherapy.

## Contribution

This case report presents a rare instance of intradural extramedullary thoracic spinal paraganglioma in a young adult.

## Key findings

- The patient showed complete recovery of motor deficits after functional rehabilitation.
- Radiological follow-up showed no signs of tumor recurrence one year post-radiotherapy.

## Abstract

Spinal paragangliomas are rare, typically benign neuroendocrine tumors, exceptionally uncommon in the intradural extramedullary thoracic region. Their diagnosis is particularly unusual in young adults. We report the case of a 27-year-old patient who presented with progressive paraparesis due to spinal cord compression caused by a 36 × 17 mm mass at the D3-D4 level, identified on MRI. Surgical resection was performed. Pathological examination confirmed the diagnosis of spinal paraganglioma, supported by immunohistochemistry (positive for chromogranin A, synaptophysin, and focal expression of S-100 protein). Given the risk of local recurrence, adjuvant radiotherapy was administered. Clinical outcome was favorable, with complete recovery of motor deficits following functional rehabilitation. Radiological follow-up at one year post-radiotherapy showed no signs of recurrence.
